The correct answer is A.

I don't understand how you reduce 96^2 to (2^5*3)^2. 96*96 = 9216. (64*3)^2 = 36864. Am I missing something? How are those equivalent?

A = 3
B = 6
C = 9
D = 12
E = 18

I tried to read through this post here: https://www.beatthegmat.com/can-someone- ... 16619.html but I just don't understand the math.

This is really just an exercise in breaking down 96 into a product of primes:

96 = 2^5 * 3^1

Let's also do the same for 8:

8 = 2^3

Applying this to the problem at hand...

(8^2)(3^3)(2^4)/(96^2)=((2^3)^2)(3^3)(2^4)/((2^5 * 3^1)^2)=(2^10)(3^3)/[(2^10)(3^2)]

Now we can start cancelling out terms:

(3^3)(2^10)/[(2^10)(3^2)] = 3


Answer is A

2^5 is 32, not 64
