Answer 1

\[(5a)^4\] ? is that the question?

Answer 2

replace a with 2. Raise 2 to the 4th power. Multiply that answer by 5

Answer 3

Yes Usaki Doll

Answer 4

then if a = 2... 5(2) = 10 and then that is 10^4 which is a very big number and not a choice on here.

Answer 5

Well then, multiply 5 by2 and raise 10 to the 4th power. But that is not one of your answer choices so that is obviously not what the problem is.

Answer 6
