B. larger than expected answer.

D. opposite in sign to the expected answer.
E. in variance with x.

Should be C. xsqrt3^2 or x2sqrt3

(x)2/3 or (x)2/3 either way

C

seems hard, but just plug in a number. i.e. 8
8^1/3 = 2; 2^2 = 4
8^2 = 64; 64^1/3= 4

they are the same...

I agree. should be C

(x^1/2)^1/3 = (x^1/3)^1/2. Both are x^1/6
