I'm assuming that you're asking about


\sqrt[5]{4x^2}\cdot\sqrt[5]{4x^2}

If this is the case, you need to use the following rule:


\sqrt[a]{b}\cdot\sqrt[a]{c} = \sqrt[a]{bc}

In other words, if the roots have the same order, the multiplication of the roots is the same thing as the root of the product of their content.

So, we have


\sqrt[5]{4x^2}\cdot\sqrt[5]{4x^2} = \sqrt[5]{4x^2 \cdot 4x^2} = \sqrt[5]{16x^4}
