The first step to solving this expression is to factor out the perfect cube
[tex] \sqrt[3]{m^{2} n^{3} X n^{2} } [/tex]
The root of a product is equal to the product of the roots of each factor. This will make the expression look like the following:
[tex] \sqrt[3]{ n^{3} } [/tex] [tex] \sqrt[3]{ m^{2} n^{2} } [/tex]
Finally,, reduce the index of the radical and exponent with 3
n[tex] \sqrt[3]{ m^{2} n^{2} } [/tex]
This means that the correct answer to your question is n[tex] \sqrt[3]{ m^{2} n^{2} } [/tex] .
