x^(3)= (125)/(27)

To solve for x, we have to get rid of the
^3 so we do the opposite which is
\sqrt[3]{}


x = \sqrt[3]{ (125)/(27) } =  (5)/(3)

The reason it's just positive and not ± is because since it is multiplied by itself 3 times, so if it were to be negative, the fraction would be negative.
