Your desired result is only correct in certain cases.

FullSimplify[(a^2)^(3/2), Element[a, Reals]]
Abs[a]^3

FullSimplify[(a^2)^(3/2), a > 0]
a^3

if I enter:

FullSimplify [ (a^2)^(3/2) ]

(in correct MATHEMATICA syntax, the program does not yield the correct
result, a^3 ... 

why is that?

thanks!
