I narrowed down the answer choices to D and E. To me it was a toss up and I would have just ended up guessing if this was on the actual exam. Can someone please explain to me why D is incorrect?

Practice Quant problem

I'm having difficulty figuring out the solution to this problem from one of the GMAT practice exams:

If xy=1, what is the value of {2^[(x+y)^2]}/{2^[(x-y)^2]}?

A. 2
B. 4
C. 8
D. 16
E. 32

Any help/advice would be much appreciated!

Hi Brent, thanks for your explanation. The brackets around the answers was not even something I was looking at when answering the question. Is it typical of GMAT questions to have little tricks like these for their solutions?
