Change the expression to an equivalent expression in radical notation. Assume all variables are positive

Take into account that tany expression of the form f(x)^m/n, can be expressed as follow:
[tex]f(x)^{\frac{m}{n}}=\sqrt[n]{f(x)^m}[/tex]then, for the expression (4y)^2/5, you have:
[tex](4y)^{\frac{2}{5}}=\sqrt[5]{(4y})^{2}[/tex]
