how do i rewrite with positive exponents, assuming that even roots are of nonnegative quantities and that all denominators are nonzero

Question

(10xz/11y)^-2/3

Answer 1

Because the exponent is negative , you can flip over the fraction inside parenthesis in this case:

 

  (11y/10xz)^(2/3)

 

You then take the cube root, then square it
