Question 653228
"simplified" means a lot of things.  When exponents are involved, it means "no negative exponents".

Any negative exponent on the top (numerator) of a fraction becomes positive on the bottom (denominator).  Any negative exponent in the denominator becomes positive in the numerator.

You have:

(2^5)(2^-7).  This is all in the numerator.  We can rewrite as:

(2^5) / (2^7)

Now, where are there more 2's?  
In the denominator.
How many more?
2 more.
So, there is 2^2 more in the denominator.

Therefore, the answer is 1/(2^2) or 1/4.
