Oga how can log2 and logx cancel one another,ojoro gbagbe theorem,I aint eating that pooo

So when are you going to use that in real life?

Abeg maths, i have my own problem to solve. I dont have time to solve yurs now.

how can log2 and logx cancel each,haba is not dimensional balance ur solving is mischief

Solution:
Upper limit of the set = 50
n + r = 50 + 5
n + r = 55
n = 55 - r
from St 2.
n × r = 750
but n = 55 - r
hence,
r(55 - r) = 750
r² - 55r + 750 = 0
r² - 30r - 25r + 750 = 0
r(r - 30) -25(r - 30) = 0
r = 30 Or 25.
but n + r = 55
for r = 25
n = 55 - 25 = 30.
for r = 30
n = 55 - 30 = 25.
but n + r > 50 by 5.
if r = 25 and n = 30
25 + 30 = 55 > 50 by 5.
and from the question, n > r.
so the right evaluation to be used is
r = 25 and n = 30.
Now, nPr
nPr = n!/(n - r)!
nPr = 30!/(30 - 25)!
nPr = 30!/5!

Correct G!!

He get 1 day wey ah dey solve math! Dey ask me say make ah 5n p2! And ah ryt am 4 ma buk say psquare dey studio!!

I hate Maths like I hate APC...

the sex of a set is integral to the surfasion fx = x3S

this is harder than d hardest....lol
the probability of finding at least a grasshopper in a circular field is 0.99, if the expected value of grasshoppers in 2 per cm squared, determine the radius of d field. not sure if d expectation is correct... U can just state how u will do it

This is just a try, you can review the solution and answer while we wait dor maths gurus to come try it too.....

I beT that question is for naturalwaves. The dude I quoted.

If you add the age of a man to the age of his wife,
the result is 91. He is now twice as old as she was
when he was as old as she is now.
How old is the man and his wife?

Dis is exactly y i hate MADmatics....it looks really crazy i cant underrstand a thng.Tell d answr and i'd still found it difficult 2 get it yet.#effect of MADmatics#

You do not hate maths... You are just too lazy to sit down for hours doing calculations

Lagos. You?

mployer:


The ans is 2.21E30

ie 2.21x10^30

Ok, I envy u guys

These days I don't stress my brain any longer to solve equations the ones I did at school don do abeg.....na money equivalent I can calculate perfectly...just change that equation to cash and see me give you answer without pen papper or calculator

Does anyone know d code for etisalat BB subscription?

Benin. It would have been nice to have you reboot my brain. Loved mathematics like mad before... changes happened to me.

naturalwaves:

Lagos. You?

Its an undefined cult, math is easy but dey make it difficult, cult!

I think if there are 2 GH in 1 cm^2, then in A cm^2 there shld be 2A not A/2 grasshoppers. like
2=1
x=A
so x(1)=2A

bataderemi:

This is one of d ojoros that I mentioned sir, the part where u cancelled out d log, it ought to be 2^(x-2) not 2(x-2) tks.

You may be correct sir. Let me know if you have a better solution.

. This one is for people like us who never liked maths.

Thanks for reminding me of the good old play days.

Yeah, that will be 44/7 . Thanks. Let me edit.

I don't actually. nice try tho

[quote author=mployer post=29072987]

The ans is not 2.228 [/quo te] u r wrong ; the ans is 30P25 which is 2.2104E30 where P denotes permutation and E is exponent

dejt4u:


(n, r) = (30, 25) since n+r = 55 (that is, their sum is greater than the upper limit of the set by 5)..
³⁰P₂₅ = 30!/5! = 2.21 E 30

Congrats! I don't understand maths at all. I wish I either had better teachers or paid more attention.

naturalwaves:

aiit... what are u studying?

Some thing we can learn from on FP

@OP u call this hardest math ever have u seen questions on Real Analysis? Such an abstract course...

Solution:
Upper limit of the set = 50
n + r = 50 + 5
n + r = 55
n = 55 - r
from St 2.
n × r = 750
but n = 55 - r
hence,
r(55 - r) = 750
r² - 55r + 750 = 0
r² - 30r - 25r + 750 = 0
r(r - 30) -25(r - 30) = 0
r = 30 Or 25.
but n + r = 55
for r = 25
n = 55 - 25 = 30.
for r = 30
n = 55 - 30 = 25.
but n + r > 50 by 5.
if r = 25 and n = 30
25 + 30 = 55 > 50 by 5.
and from the question, n > r.
so the right evaluation to be used is
r = 25 and n = 30.
Now, nPr
nPr = n!/(n - r)!
nPr = 30!/(30 - 25)!
nPr = 30!/5!

Expo !!
After u don peep answer from Above.

naturalwaves:

Yeah, he's very correct bro because if
(a + b) log x = log b, then
log x ^{(a + b)} = log b and
x ^{(a + b)} = b. (log 10 cancels each other)
Having said this, I thin the only logical solution to this is the graphical method. One has to draw a graph of y = 2 ^x and y = 4x on the same axis.
