If

, then
![\sqrt[2]{y}=\sqrt[2]{x^2}=x](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7By%7D%3D%5Csqrt%5B2%5D%7Bx%5E2%7D%3Dx)
if

, then
![\sqrt[3]{y}=\sqrt[3]{x^3}=x](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7By%7D%3D%5Csqrt%5B3%5D%7Bx%5E3%7D%3Dx)
ok

so
![\sqrt[2]{64}=\sqrt[2]{8^2}=8](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B64%7D%3D%5Csqrt%5B2%5D%7B8%5E2%7D%3D8)
![\sqrt[3]{64}=\sqrt[3]{4^3}=4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B64%7D%3D%5Csqrt%5B3%5D%7B4%5E3%7D%3D4)
well, the cube root usually bigger
Have to multiply 3 times here. Let's begin by mult (2x^4)/(y^4) by (3x^3y)/(zy^3):
3*2 = 6
y/y^3 = 1/y^2
x^3*x*4 = x^7
z*y^3*y^4 = z*y^7
So, the product is
3x^7*y 3x^7
----------- and this can be reduced once more: ----------- (answer)
z*y^7 z*y^6
