It doesn’t matter. Since this is an EXCEPT question, we’re just trying to find values of n that cause each expression to fail. Without any restrictions on n, we are of course free to test odd numbers, even numbers, or non-integers..

because using a calculator is definitely a "math error" on the GMAT - one that will get you disqualified!

Hi, spent a lot of time to decipher, but could not. I picked 1 & 2 and checked for each of the options and got the below:

The Question as well as each ans is confusing, for eg. - how can 1/2 = -2 in result (B) below (or is my understanding itself is wrong?)?

If n=1:
A) -2 = -1/2
B) 1/2 = -2
C) 2 = -1/2
D) -2 = -2
E) -1/2 = -1/2

If n=2:
A) -4 = 1/4
B) 1/4 = 4
C) 4 = 1/4
D) 4 = -4
E) 1/4 = -1/4

Can someone explain please.

Thanks
Sunil
