A) (1/2)^(-48)

C) (1/2)^(-6)
D) (1/8)^(-11)
E) (1/8)^(-6)

OA: B
(1/2)^(-1) x (1/4)^(-2) x (1/16)^(-1) = 2 * 2^4 * 2^4 = 2^(4 + 4 + 1) = 2^9 = (1/2)^ -9
I think you have made an error in either copying the question prompt or the answer choices.
Can you please recheck and correct the question.

As for the solution, always remember 2^(-1) = 1/2
By keeping this in mind, you can solve this question.
