# Thread: Cube root problem

1. ## Cube root problem

Hey guys, so my final is in 3 hours and I'm working on my review and there are a few I need help with, I appreciate it. The problem I'm stuck on is find the cubed root of (16x to the 4th,y to the 3rd,z to the 6th) . I'm on my phone and I can't use the math icons but you obviously know what I meant as the problem with a radical bar. Thanks for any help!

2. It seems pretty clear, but just to be sure, you mean to simplify the following:

$\sqrt[3]{(16x)^{4}y^{3}z^{6}},$

right? If so, what ideas have you had so far?

3. The rule you need is (x^ay^bz^c)^d= (x^(ad))(y^(bd))(z^(cd)) . Now what power is a cube root?
