PLEASEEE HELP! What is the simplest radical form of the expression? (8x^7y^4)^2/3

Answer:
4x^4 y^2 ∛x^2y^2
Step-by-step explanation:
[tex](8x^7y^4)^\frac{2}{3} \\\\8^\frac{2}{3}(x^7)^\frac{2}{3}(y^4)^\frac{2}{3}[/tex]
[tex](2^3)^\frac{2}{3}x^7*^\frac{2}{3}y^4*^\frac{2}{3}\\4x^\frac{14}{3}y^\frac{8}{3}[/tex]
