Divide a^3 - a - 7 + 7^a by (-1 + a^2)
A -a^3 + 7a^2 - a - 7
B -a^2 -7a + 7
C a - 7
D a + 7

The answer is definitely (a + 7) which is D. . . .though you made a typo error when typing 7a^2 and not 7^a

bad guys dominate here. Each time i enter here, i always have headache. Mr ortarico and co, good evening mr genius and nus (laffin gas) good evening. Pls am still in need of someone dat we can read together ooo expecially mid night through free night call. Seven of my friends,including me did this during our waec and it really helped.

Good evening boss, I'll like to be part of the group study. Though calculusf(x), mr calculus and I are doing that I'll join you. Nice one!

let's increase in number den by me joining d winning team, just 2 do our own tutorial, lolz

Wow, not surprised and no doubts boss!
Please can you help me look into this boss, cause i'm yet to understand it's solution well:
Divide 2²ⁿ - 3n - 1 by 9. . . . . . .thanks!

The question is the same as (4ⁿ-3n-1)/9 all the variables are divisible by 9 except 4ⁿ because they are not in equal base, so to put them in equal base we ask that 3^x = 4 by logarithm we know that xlog3 =log4, x=log4/log3 3^(log4/log3)=4 now that we have a common base, the answer now becomes, since log4/log3=1.26 so(3^1.26n-3n-1)/3²= 3^1.26n-2-1/3 - 1/9

Simple but pple will miss d spelling. w@ is d full meaning of WAEC, NECO and JAMB. WRITE UR ANSWERS WITH CORRECT SPELLING. abeg no google ooo

Well boss, our workings are almost the same. Here's the solution the dude gave me in some pages back:

buzyguy: Suppoz n=k,2^2k-3k-1=9m........(*) whre m z an integer whch z true 4 n=k+1 then,
2^2(k+1)-3(k+1)-1=2^2k.2^2-3k-3-1
=2^2k-3k-1+3(2^2k-1)
=9m+9/3(2^2k-1),frm (*) above then,
=9[m+1/3(2^2k-1)] ans. Fedpoado putme last yr

Unilag To Use 200 As Cut Off Mark Instead Of
180 - VC
21.06.2013, 10:02 Education
The Vice Chancellor of the University of Lagos
Professor Rahamon Adisa Bello has just
announced that the school will make changes
to their JAMB Score
Admist the Official Cut Off Mark
Reduction released by JAMB, The Vice
Chancellor of the University of Lagos
Professor Rahamon Adisa Bello has stated that for
the conductance of its forthcoming POST UTME
Exams, it will only accept a JAMB score of 200 and
above
The vice chancellor also noted that JAMB had given
the various univesities the power to set a higher
cut off mark above 180 but not below it.

Good morning all

this guys solution is to complex, and this question requires basic mathematics just as i have shown, see the reason i don't like people using advanced mathematics where unnecessary , that is why you will see that most of my solutions are only in a lay mans format.
