2 to the power of (7/2) can be written as sqrt (2^7), since the 2 on the bottom of the exponent can be turned into a root.

Then, since sqrt (2^7) is the side length, we square it to get the area. If you square a square root, they cancel out, so you are left with 2^7 = 128 inches squared.

The answer is choice (B).

Answer:

128 square inches
