Question

Rewrite with positive exponents. Assume that even roots are of nonnegative quantities and that all denominators are nonzero.
(2x^(-1/2))^3

Answer 1

\[(2x ^{(-1/2)})^{-3}\]

Answer 2

All a negative exponent does is move it to the denominator so
first 1/(2x^(-1/2))^3
then 1/(2(1/x^(1/2)))^3

Answer 3

then you can simplify to
x^(3/2)/8
