I assume the expression is $\sqrt{x^4 y^5} \times \sqrt[3]{x^2 y^5} \times \sqrt[5]{x^5}$.

The latex code for this is $$\sqrt{x^4 y^5} \times \sqrt[3]{x^2 y^5} \times \sqrt[5]{x^5}$$

Now, assuming that the formula is what mr. fantastic said, what is your question?

simplify first

$(\sqrt{x^4y^5})(\sqrt[3]{x^2y^5})(x)$

then change everything to a common power

$\sqrt[6]{(x^4y^5)^3(x^2y^5)^2(x)^6}$

can you finish up?
