Thanks for the reply..
but the Question in the Practice test doesn't say, 2^((x+y)^2)/2^(x-y)^2
It says, 2(x+y)^2/2(x-y)^2. Thats what got me stumped.
Is it a misprint on the Test itself? Is it possible?
I lost quite some time on this one.. as I thought I was missing something very simple on it.
Yes there is a typo in question stem
You are not alone stucking with this problem
