Something to the power of 1/n is the nth root of the something. 1/4^1/2 is the square root of 1/4

You can of course compare 0.4^3 with 4^3, in the latter you get the result of 64 which is sort of similar to what you were asked.

(1/2 *1/2 = 1/4)
as for 0.064^1/3 convert decimal to fraction 64/1000 and cube root
0.064^1/3 = 4/10

X^1/2 = 1/(square root X)
Anything raised to a third is one over cube root of X. e.g.
X^1/3 = 1/(cube root of X)
