What is the following sum? 5 x open paren cube root of x squared y close paren plus 2 times open paren cube root of x to the 5th power y close paren

Rewrite the second cube root by factoring out a perfect cube: ∛(x⁵y) = x∛(x²y). The expression becomes 5x∛(x²y) + 2x∛(x²y), so adding the like terms gives 7x∛(x²y), which is choice D.
