[jstern31]

If the integers a and n are greater than 1 and the product of the first 8 positive integers is a multiple of a^n, what is the value of a?

1) a^N = 64
2) n=6

I'm not sure what it means by "the product of the first 8 positive integers.."

what question says : 1*2*3*4*5*6*7*8 = a^N (k)

lets go option by option,
1 2 3 2 2 5 3 2 7 2 2 2
First take option (2) : N = 6

simplify the phrase as: 1* 2^7 * 3 ^2 * 5 * 7 * 8

so i can say 2 ^ 6 (k)

which means A =6, this is SUFFICIENT, so answer can be B or D

Now option (1): a^N = 64

so it can be 2 ^ 6 or 4 ^ 3

this is INSUFFICIENT

Correct answer should be B,

what is OA?

yea, it's B. Thanks for explaining.

I feel like I could have done that if I understood what it was asking, do you think on the real GMAT questions will be worded so confusingly?

I think the Quant OG level is not upto the mark, but if you see GMATPREP level of Quant questions is good which is the best simulation for actual GMAT, i recommend one must go through them
