What is 2 3/2 equal to?

A.2sqrt8

B.3sqrt8

C.3sqrt16

D.2sqrt16

Is it c? I'm not 100% sure on how to solve this.

asked by Laney
  1. 2^(3/2) = 2*2^(1/2) = 2√2
    or, since 8=2^3,
    2^(3/2) = √(2^3) = √8 = 2√2

    I suspect a typo

    C is 3√16 = 3*4 = 12

    None of the choices is correct
