Nastydroid:U can't use 3*3 method just like that. You know in 3*3 method, when you take out each term, u will multiply it by remaining 4 terms in the bracket which will be evaluated. You will do something similar to that here. From the 5*5, you will bring out a term and have 4*4 in each bracket and the reduce the 4*4 to 3*3 through the same method and the 3*3 into 2*2 before you solve and get final answer.It could get complex and requires attention. Study what I solved though I am still waiting for agentofchange to come confirm if it is correct. |
agentofchange1:Infact, over correct dey worry your solution. Thumbs up man. That's the answer. Send a PM to get your gift. Your approach was even totally different from mine but we got the same answer. That's the beauty of mathemtics. See mine below;
|
agentofchange1:Well, I got. "-140" as my answer. If that is wrong, then, I must have made a mistake in the calculation. See my solution below,
|
agentofchange1:Okay. |
agentofchange1:Hmmm. |
agentofchange1:Is this a 5*5 matrix and do you want us to find the determinant? |
agentofchange1:Hahaha benbucks, I knowingly didn't mention the maths gurus in the house. The prize is just a recharge card token if it is correct. |
^^^ That's not the answer. Show it to your friends. |
TRADELYN:Happy new year to you too. You tried but your approach is wrong. You see, squaroot(a+b) is not the same thing as squaroot(a) + squaroot(b). E.g squaroot (15+10) = squaroot(25)= 5 but squareroot (15) + squaroot (10)= 7.035 which is not the same as 5. Try again. |
alabiyemmy:No. Try again. |
PapiDShipCapt:Answer must be in surd form and you must show workings as well to get the prize, so, calculator won't be useful. |
Surds are very common with respect to mathematical basics and very important as not all roots of numbers can be expressed as entirely whole numbers hence, the reason for the concept of "surds". Ladies and gentlemen, I present to you a simple but trickish question on surds below. The first person to solve it correctly gets a prize. Goodluck! Cc: olawalebabs, Richiez, Fynestboi.

5!= 5*4*3*2*1=120 handshakes can be exchanged and 20 handshakes are exchanged. The question needs to be more specific on how the handshakes is gonna take place. |
akoji1:No, after tax. I am talking about your take home pay after all deductions. |
akoji1:You are welcome. I will add you and give her your pin subsequently. She is in the best position to put you through. |
Lawatog:Sure, Access pays more than GTB. The only bank that I know pays better than Access is Diamond bank but I don't have the precise figures for GTB. |
akoji1:Yeah, and you have to be very careful at the training school, don't be carried away. You must not score less than 65% in each of numerous courses, you can retake a failed course just once and you must pass it the second time. You also have to follow all instructions strictly particularly during exams because once you err, you would be automatically dismissed and that's the end, they dismiss people at the slightest misconduct and this is not the time to go start dating your classmates, you need concentration. You will enjoy the training, the meals, the fun, outings etc. If you score best in any of the courses, you will get a gift. There are fantastics prizes for overall 1st,2nd and 3rd positions. All the best to you! |
akoji1:Very true. You will get 43k per month during your 4 months training and at least 237k per month after training when you resume. My lil sister works there. |
I was gonna slap the OP if UNAAB (FUNAAB) didn't make the list. There is no how you will talk about best Unis in Nigetia and Funaab won't be there. Moreover, it is even underated. Funaab is far better than most of these federal unis on the list. |
2sExy1:Hahahaha. The ojoro wasn't intentional you know? I have some other challenging maths problems which I was able to solve. I will open a thread for it subsequently and attach a prize to it. Nice day! |
2sExy1:That's what we are saying bro. The rule I used there is wrong.I hurriedly tested it for two values and it worked, so, I didn't bother testing for other values again until mathefero pointed it out. I tested it for values of 2 and 4 . E.g. If 2^(X) = 4, I said X = sqrt 4 = 2 and if 2^ (X) = 16, X = sqrt of 16 = 4. Unfortunately, it was just a coincidence that we got the same answer as the rule is wrong. When you test it with 2 ^ (X) = 8, you know X is supposed to be = 3. If I now say, X = sqrt 8, I won't get 3.So, the rule I used is wrong and we have to find another way to solve that problem. |
dejt4u: ![]() |
mathefaro:Yeah, you are right, it should be if X^2 = P, the X = sqrt (P). That was what was on my mind. Although, I tested the rule with values of 2 and 4 and it worked, that was why didn't bother testing with other values again. Thanks for pointing it out. Men, I no go chop today o. |
^^^^^^^^ The same method works for 3^X = 9X when solved to get X = 3. Solution attached below;
|
franciseromosel:Hi everyone, I have finally solved this 2^x = 4x question in the most simple, straighforward way that is devoid of any ojoro. Lol. Find the solution attached below; CC : Nastydroid,XXX5, bataderemi, 2sExy1, bayulll01,matherafo, dejt4u,Elantracey.

Hmmm. So funny the way way everyone comes up with a list everytime. ![]() |
divAnnie:You are welcome! Constant reminder/ refreshing of concepts put in memory is very important lest it undergoes effervescence ![]() |
Gerrard59: |
Gerrard59:I think the function is continuous but not differentiable at x= 1 cos after differenciating f(x) , there was no place to slot in 1 at all as it gave outright figures. Check what I got below and review with colleagues as it has been long I did this.
|
rapins:That should be 121 then. Co-incidentally, that was the the answer I used to get an " S" first time. Check your mail. |
XXX5:Did I get it? Did you get my mail? Although, the formula before the last is supposed to read "30- sqrt(81) and not sqrt of 21, I was still able to work around it. |
