4 to the fourth power just means 4x4x4x4 and then the answer. So if you wanted to find the answer all you have to do is do 4x4 which is 16. Then 16x4 then find the answer. And then the answer to 16x4 times 4.
40 + 24 = 64
(2x - 3)(2x + 3)(4x2 + 9)
16' x 4' = 64 square feet
The answer is 4x4=16 16x4=64
