Questions 1 and 3 are not clear! I will type out the solutions for 5 and 6 later!

I hope it helps.

Question 2

2^x + 32{2^(-x)} - 12 = 0

Rearranging gives :::>

2^x + 32(1/2^x) - 12 = 0

Put 2^x = s

Substituting into the equation gives us:::
s + 32/s - 12 = 0
s² + 32 - 12s = 0

:. s² - 12s + 32 = 0
Factoring gives :::

s² - 8s - 4s + 32 = 0
s(s - 8 ) - 4(s - 8 ) = 0
:. s - 8 = 0 or s - 4 = 0

s = 8 or s = 4

Recall that s = 2^x
Putting back gives :::>

2^x = 8 or 2^x = 4
2^x = 2³ or 2^x = 2²

Thus ::::>

x = 3 or x = 2


Question 4

{3ⁿ - 3^(n-1)}/{3³× 3ⁿ - 27 × 3^(n-1)}

Let's first apply the law of indices ::::

3^(n - 1) can be rewritten as ::: 3ⁿ ÷ 3¹
= 3ⁿ ÷ 3

So that the expression becomes :::

{3ⁿ - 3ⁿ ÷ 3}/{3³× 3ⁿ - 27 × 3ⁿ ÷ 3}

Then let's put 3ⁿ = s

Substituting 3ⁿ = s back into the expression will give us :::

{s - (s ÷ 3)}/{3³× s - 27 × s ÷ 3}

Factoring s in both the numerator and denominator, gives ::::

s{1 - (1/3)}/s{3³ - 27/3}
with s cancelling out, leaves us with::::
:. {1 - (1/3)}/{27 - 9)
= (2/3)÷18
= (2/3)(1/18)
= (1/3)(1/9)
= 1/27

Do you know what it takes to have a first class engineering degree in a Japanese university? He must be a genius in the applications of maths and physics!! Ignorant of you to even mention Harvard, is Harvard known for engineering or business and law? Don't Bleep with the Japs and Germans in this field of engineering!

Your ignorant self even recognised the bullshit you said and is threatening lagoon to avoid repraisals.

Back to the topic, the dude did great. It's not news about Nigerians being sentenced to death for smuggling drugs into asia this time around.

You dey mind that cretin? You get time bros!

He thinks Japan is Cambodia Smh!

PervyByNature:
I'm sick of hearing people call G.E.J a hero, the guy lost, what is expected of a looser?? No be to surrender? Even with the trillions he spent, he lost with a wide margin, now tell me, do ya'all think he doesnt know that if he doesnt accept defeat he wont even live to tell the tale? The fact that Dis guy lost and accepted defeat doesnt make him a hero, it simply makes him a good looser. QED

Gbam!

Clean post, on point bro!

Omotayor123:
I don't understand why youths will prefer going to such institution. I call it Laziness on their part. There are hundreds of other federal Universities for both young nd old.
Most of the Noun 'youth' students I know are those that have failed in one institution or d other.
Go nd get ur facts#

Na now I understand you At least the bold explains your stance! Well, maybe that's only because it's in Nigeria...Nigerians love easy things, shortcuts etc; so I get it LOL

Omotayor123:
True! Education has nothing to do with Age. But Noun was specially founded for working class Adult. Check out Jamb brochure *
Noun was listed under specialized institutions.
That's Why I Made d earlier comment. The Youths in Noun should av known Better.....

Oh well; I don't know about the bold, but I still believe that it's wrong and unlawful to exclude NOUN youths from serving the Nation!

NOUN is an accredited Federal University; so, it's graduates should be accepted into the NYSC just as graduates of other accredited institutions abroad are accepted for youth service regardless of whether the college is for youths or working adults!

And to be sincere with you, I have never heard anywhere in the world that a school is founded "specially" for working adults; even if there is, it will be illogical to deny youths who attend it youthful privileges because it's a working adult University. It's only in cases of Military Universities that age requirement is applicable for those who intend to serve in the Military after graduation!

I believe NOUN like other distant learning centres/institutions was NOT founded "ONLY" for working adults but was created to help working adults study at home as most of their lectures and exams are delivered online! This can as well help youths who want to work full-time handle their studies at the same time; so it's not only meant for working adults!

Omotayor123:
They don't have a point. The school was Originally meant for Adults #

Says who? Education has nothing to do with age!

Last I checked, it was the Federal Government that created the University and accredited it in the first place; so, why unjustly exclude those who graduated at 30 years of age and below from serving the Nation? That's utter lawlessness! Let them obey the laws of the land and do justice to this issue...that's all!

Lawless Country! Smh...

Weah96:
This life is temporary. Beggars and billionaires alike will all feed the worms with their decomposed bodies. The other life, they say, lasts forever. Why do you care about your condition HERE on earth? It doesn't make sense. You can't have your cake and eat it too. If you communicate with Jesus, even if you're out begging in the streets, you shouldn't care. Who are you trying to impress by NOT begging? The hell bound people with their fancy toys?

Jesus himself placed a scale of difficulty on the probability of rich people joining him. It's easier for a camel to go through the eye of a needle, he said.

Did Jesus tell you to be rich like your prosperity pastors?

Nice!

You understand the words of Jesus Christ even better than the OP who claims to be a child of God Smh!

bros trust all is well with you

I'm cool o jare bros sukkot! Wetin you chop remain?

so would the beating have been justified if the soldier was holding a phd ?

Good question bruv!

Anaskie:
Nigerians are really funny. Someone decides to criticize corruption and he's now the bad guy?

By the way, if you had the money won't u also send ur children to school abroad? I'll certainly do that if I had the cash.

Who'll like to go thru the stress associated with Nigerian universities; from lecturers' intimidation, cultism, incessant ASUU strikes etc?

And what in the world is wrong with the Galleria showing foreign movies? Lyk seriously?

Gbam!

Couldn't have said it better bruv!

<<< the typical Nigerian. you know sometimes i think the suffering of Nigerians is deserved. God knows what he is doing and he is not the author of confusion. to a wicked people will he give wicked leaders. especially after reading this whole thread. from now on when i see suffering Nigerians i will laugh. the suffering of Nigerians will be a source of joy to me from henceforth. cuz you have to be wicked for God to put you in that position. Nigerians as a whole are a wicked people

proverbs 1 vs 26 I also will laugh at your calamity; I will mock when your fear cometh;

zechariah 11 15 And the Lord said unto me, Take unto thee yet the instruments of a foolish shepherd. For, lo, I will raise up a shepherd in the land, which shall not visit those that be cut off, neither shall seek the young one, nor heal that that is broken, nor feed that that standeth still: but he shall eat the flesh of the fat, and tear their claws in pieces. <<< ALL YOUR WICKED LEADERS ARE SELECTED TO BY GOD BECAUSE YOU ARE A WICKED AND EVIL PEOPLE.

NOW THE LORD HAS DECIDED TO EASE YOUR PAIN BY BRINGING IN SOMEONE LIKE BUHARI, BenBruce etc TO BRING YOU ACROSS THE RED SEA, TO HELP EASE YOUR PAIN BUT YOU WICKED PEOPLE LIKE THE ISRAELITES STILL YEARN FOR THE WAYS OF EGYPT. [b]THE DAYS OF OLD. ITS BECAUSE YOU ARE WICKED. THIS IS HOW YOUR WICKED MIND THINKS. YOU HATE JUSTICE.

This is exactly why I love the above post, by buzugee! Nigerians are wicked people, that's why they suffer...Imagine folks bashing a man who was only pointing out one of the major challenges we have in the Country!

How can you Nigerians ever be happy and your economy prosper when some of you are busy supporting and calling corrupt leaders like GEJ "MY HERO"; A man who once said "STEALING IS CORRUPTION"? Smh!

Greedy and selfish people who only give their mind to thinking on their belly? People who only see our national treasury as food that should be shared amongst their obsessed and gluttonous selves? Folks like that should never be celebrated for any reason whatsoever!

Sorry Bro!


And a man's enemies will be the members of his own household - Matthew 10:36; Even King Jesus agreed with that fact!

For me, these ones are the best!

SirShymexx:
I'm sorry, Mr. Dunderhead, I don't do illiterate-speak.

I just speak based on reality, and if it's about listing just anyone in a backwater University, then you should be able to list at least a thousand of them with ease.

I was expecting distinguished academics, top of the pops, not just anyone.

Based on this list - even Sierra Leone should be able to produce a far better list than this one.

Like I said earlier: only two (or maybe three) of them are distinguished academics. Thank me, later.

Exactly bruv!

missclasssy:
This isn't an article in that sense. I was the one that compiled the list. I did my research and I came up with it.

I wasn't biased in any way.

Oh okay; you researched it yourself? Cool, I get it! But to say it's not biased is very funny my friend!

tonychristopher:
Abi north dey go school before?


Even WAEC,JAMB,NECO, UN MDA Goals have proved igbo position on education and human capacity, do you want link?

LOL Your ignorance is alarming

Smh!

ziqqz:
Hm! The Ibo tribe...
Outbraining Nigeria since -100,000BC

Just because majority of them are Igbos doesn't make them smarter than other tribes! The research looks biased and one sided to me; if you notice, 95% of the Profs either studied or are teaching in the US...What about other academicians of Nigerian descent in the UK and other advanced Countries/top Universities around the globe?

And for the fact that it's only one Prof from the whole of Northern Nigeria shows how biased and shallow the OP's research was!

Mtchew!

i did a levels in d uk. my sisters attends uni of Birmingham. shes is spending four years . cos she started wit foundation. u cant use ijmb to compare alevels na. dey look similar tho. but ijmb is nt in d same level

Tah! IJMB's standard is way better than UK A-Levels! I passed Cambridge A-Levels with distinctions in Chem, Phy and Mth studying at home the same year I took JAMB so I know their standards! If your sister is spending 4 years, it's probably because she started with foundation course or maybe she's studying a professional course like Engineering, Pharmacy etc.. Generally, if it's not a professional course, most UK univs are six semesters (3 years) for students with 9ja O-levels and good IELTS or TOEFL scores. Heck some colleges squeeze the 6 semesters program to less than 3 years for courses like computing, IT etc...

I have seen IJMB past questions and If not for expos in 9ja and all? You can't compare IJMB with UK A-Levels. Serious students who passed through IJMB are way better and cannot be compared with some UK A-Level dudes! The irony of the whole thing is, after wasting years studying professional courses in 9ja Uni, your counterparts in other Countries that spend a few years studying the same thing would be better than you! Smh..

ednut1:
is utme a course ? if u use o levels to enter uk uni. u wud start wit a year foundation before proceeding to d 3 year course

I know UTME isn't a course; I was only comparing their standards. A-Level is kind of like 9ja IJMB which is only 9 months in Nigerian Schools (After which you can use it for 200L direct entry into 9ja Univs) compared to the 2 years in the UK.

Foundation after enrollment with 9ja O-levels? Hell, no!! It depends on your course of study though; and also if you don't have good IELTS or TOEFL scores you might be required to enroll for English Language Foundation Course! That's all!

ednut1:
in uk they do 2 years a level. nd 3 years uni. dats 5 years. Nigeria is allergic to change. make we jst dey look. our syllabus sucks. there arr some courses dat are jst repetition

UTME hard pass UK A-Levels abeg! So na still High School things e be!

That's why with 9ja O-Levels you can enroll directly into 1st year in any UK Uni. no need for A-Levels! Most of their BSc and BA courses are last for only 3 years! Only professional courses like BEngr, Medicine, B.Pharm etc last longer!

And there is no strike; same with India and most Asian Countries!

otunsman:
Dont ever call fulani herdsmen as civilians.They are terrorists.

What part of the article says the villagers killed were Fulani herdsmen for Christ's sakes? I hate it when people think with their ass-holes Smh! The villages that were attacked by those silly soldiers are occupied mostly by unarmed Plateau Christians!

Soldiers where killed in Taraba State and zombie-soldiers crossed the boarder to Plateau State for a revenge mission (probably based on the rumors they heard back in Taraba State) and massacred unarmed villagers and you are here spewing gibberish? Smfh!

ken0808:
But you expected Jonny to do it overnight...well, what is good for the goose is good for the gander. The pressure we put on Jonny to turn water into wine, we will put on you to raise the dead

Tah!!! Is six years of failure overnight to you? Jonny failed woefully! Let's give "change" a few years and see if it will fail us too. Trying Jonny/failure for another four years is tantamount to suicide!

Sai Baba!

nawtikid:
Recently, I've noticed a decline in my level of reasoning, I find it difficult to make intelligent arguments and decisions and my level of assimilation and comprehension also dropped.

Nairalanders, I need ur advice on d form of activities I can get involved in dat can exercise my brain greatly and restore my IQ.

If you know how to play chess and you've not played for a while, then start again! The game of chess is an excellent mental exercise. You can also try solving some mathematical problems if you are good at it but have not been practicing for sometime!

Feraz:
So having a blog means being in Technology?

Thanks bro, I thought I was going to see some IT gurus LOL; Naija news na joke jor!

I dey vex like say make I just hack them all now now!

Nonsense!~

omolami:
All hail our Hero; Jonathan who continue to save nigerians from bloodshead. If d court had pronounced buhari guilty the same faith that Jonathan avoided by conceding defeat could have played out again. It is fact that APC supporters are Almajiris, urchins and buchers looking for who to kill. Jonathan is noble and peaceful he went further by withdrawing the suit. What a great mind and a hero of our time. God bless Jonathan and family.

The wind of change is blowing everywhere my friend, embrace it for a better future for your kids because it's here to stay! Don't say your people are being marginalized. Joint the winning team and survive

Only uneducated folks will believe that a retired Army General who attended the NDA and many other colleges abroad is an illiterate!

It was all propaganda; deal with it bruv! Change is here to stay for the betterment of Nigeria

SO IN CONCLUSION WE HAVE PROVEN THAT ADAM IS NOT ONE PERSON BUT A BUNCH OF PEOPLE

GENESIS 5 VERSE 2 Male and female created he them; and blessed them, and called their name Adam, in the day when they were created.

WE HAVE PROVEN THAT JESUS CHRIST IS A TITLE AND NOT SOMEONES NAME AND THERE ARE MANY CHRISTS

1 CORINTHANS 15 VERSE 23 But every man in his own order: Christ the firstfruits; afterward they that are Christ's at his coming. < CHRIST THE FIRSTFRUITS

AND WE HAVE PROVEN THAT NO PERSON NAMED ABRAHAM EXISTED TOO

GALATIANS 4 VERSE 22 For it is written, that Abraham had two sons, the one by a bondmaid, the other by a freewoman. But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise. Which things are an allegory:

HOPEFULLY YOU ARE STARTING TO APPRECIATE THE FACT THAT THE BIBLE IS NOT WHAT YOU THINK IT IS. IT IS A BOOK WITH DEEP LAYERS THAT VERY FEW CHOOSE OR ACCEPT TO GET INTO BECAUSE THEY FIND THE SIMPLIFIED CHURCH TAUGHT EXPLANATION VERY EASY TO UNDERSTAND

So what will you make of this verse

Hebrews 7:4

Consider then how great this Melchizedek was. Even Abraham, the great patriarch of Israel, recognized this by giving him a tenth of what he had taken in battle.

sukkot:
ahhh but see, the bible backs me up. lets see what jesus means in the bible and lets see how many christs there are and what christ means

FIRST LETS GET THE MEANING OF JESUS

REVELATION 19 VERSE 13 And he was clothed with a vesture dipped in blood: and his name is called The Word of God. <<<< JESUS IS THE WORD OF GOD. ITS NOT A HUMAN BEING. ITS THE NAME OF THE BIBLE. SO GOD CALLS HIS WORD JESUS. IN FACT GOD IS HIS WORD. SO GOD IS JESUS

JOHN 1 VERSE 1 In the beginning was the Word, and the Word was with God, and the Word was God. <<< SO GOD AND JESUS ARE THE SAME ENTITY. HE CALLS HIS WORD JESUS BUT HIS WORDS ARE REALLY A PART OF HIM SO HIS WORD IS GOD AND HIS WORD IS JESUS. NOW WE HAVE ESTABLISHED THAT LETS GO TO THE MEANING OF THE WORD CHRIST

CHRIST MEANS TO SEAL THE WORD OF GOD IN SOMEONE. IF THE WORD IS SEALED IN YOU THAT MEANS YOU HAVE BEEN ANOINTED WITH JESUS AND THAT MEANS YOU HAVE BECOME JESUS-CHRIST WHICH MEANS THE ' MAN ANOINTED WITH THE WORD OF GOD ' .

SO JESUS CHRIST ARE THE SAINTS OF GOD WHO ARE MEN ANOINTED WITH HIS WORD SO THEY CAN GO OUT AND BE HIS REPRESENTATIVES ON EARTH. SO NOW LETS ESTABLISH THERE ARE MANY CHRISTS

1 CORINTHIANS 15 VS 23 But every man in his own order: Christ the firstfruits; afterward they that are Christ's at his coming. <<< SO FROM THIS VERSE IN THE BIBLE WE ESTABLISH THERE ARE MANY CHRISTS

MEANING JOSEPHUS AND ALL THOSE GUYS YOU MENTIONED WERE LIARS LOOKING TO GET FAME FROM WRITING BOOKS, NOT UNLIKE PEOPLE TODAY WRITING BOOKS ABOUT JESUS LOOKING FOR FAME. NOTHING NEW UNDER THE SUN

LWTMB Buzugee which kind new doctrine be this one LOL, I hope you've not reincarnated into an Anti-Christ

Truckpusher:
APC and propaganda.

GEJ has left a legacy that APC leaders would never achieve.

Instead of witch hunting Jonathan they should be concentrating on the so-called change they sold to our gullible people,Nigerians will hold them accountable.

BUT READING THIS THREAD, MOST OF YOU ARE PRAYING NOTHING HAPPENS TO HER, OR ARE SEEKING S-EX-UAL FAVORS FROM HER, OR WORSHIP HER WEALTH, OR ARE PRAYING BUHARI DOES NOTHING TO HER. ITS BECAUSE YOU ARE WICKED. THIS IS HOW YOUR WICKED MIND THINKS. YOU HATE JUSTICE.
