2 cuberoot(5(x^2)(y^4)) ? 5 cuberoot(15y^3)

Question

 
A: 50y^2 cuberoot(3(x^2)y)

B: 30y^2 cuberoot(5(x^2)y)

C: 50y^4 cuberoot(3x^2)

D: 5y^2 cuberoot(3(x^2)y)

E: 50xy^2 cuberoot(3xy)

Answer 1

2 cube root of 5x^2y^4

= 2ycube root of (5yx^2)

= 2(5x^2y^4)^(1/3)

= 2(5^1/3)(x^(2/3))(y^(4/3))

2nd part

5cube root of 15y^3 = 5ysqr15

none of the options A through E fit either question
