Amanda Giles · Answer 1

Roots take a fractional form, so the 8th root as a power is 1/8. The indices would multiply so:

x^3/8.

Jonah Bright · Answer 2

"cubed root of x squared" is " (cubed root of x) squared" = "cubed root of (x squared) "

(x^2) ^ (1/3) = x^ (2 * 1/3) = (x^ (1/3)) ^2

So the exponent or power os 2/3.
