Hello I really need help asap I don’t understand this problem!

Given:
The expression is,
[tex]\sqrt[4]{x^2y^3z}[/tex]Explanation:
Simplify the expression.
[tex]\begin{gathered} \sqrt[4]{x^2y^3z}=(x^2y^3z)^{\frac{1}{4}} \\ =x^{\frac{2}{4}}y^{\frac{3}{4}}z^{\frac{1}{4}} \\ =x^{\frac{1}{2}}y^{\frac{3}{4}}z^{\frac{1}{4}} \end{gathered}[/tex]So option D is correct.
