Simplification problem

Can anyone help me with this question please? I really can't find a way to solve it. All help will be very very appreciated!

(2^n+2) + (2^n-4)

The answer is 2^n-4 (65)... HOW? :'(
PLEASE HELP

Re: Simplification problem

I split your post from the topic onto which you tagged it. It is best that you create your own topics for your questions.

Your question is unclear. As written is appears the sum is

What does the (65) represent?

Re: Simplification problem

Was "solve 2^(n+2) + 2^(n-4) = 65 for n" intended?
