someone plz help me with dividing this radical expression!

OpenStudy (anonymous):

\[\sqrt[3]{\frac{ x^2 }{ 3y }}\]

OpenStudy (ajspeller):

You cannot simplify this anymore than it already is

OpenStudy (anonymous):

@ajspeller actually you can

OpenStudy (ajspeller):

Nothing breaks down. You can rationalize for a different form but thats about it.

OpenStudy (anonymous):

@DanJS Can you plz help me?

OpenStudy (anonymous):

@poopsiedoodle @iPwnBunnies @pooja195 I REALLY NEED HELP!!

OpenStudy (ipwnbunnies):

Yeah, I don't see how you can simplify this anymore. There are 2 different variables in this expression, can't really do anything.

OpenStudy (ipwnbunnies):

It says I'm not allowed to access the page, or something. It just looks like they added variables, they didn't find a solution of anything. Maybe I'm not understanding the problem.

OpenStudy (anonymous):

@iPwnBunnies okay this is what this website, http://rohls.weebly.com/uploads/2/8/2/1/2821453/6-2formgkey.pdf , gave as the answer for this question: \[\frac{ \sqrt[3]{9x^2y^2} }{ 3y }\] But how did they get this answer? I want to know the steps.

OpenStudy (anonymous):

\[\sqrt[3]{\frac{ x^2 }{ 3y }} =\sqrt[3]{\frac{ x^2 }{ 3y } \cdot\frac{(3y)^2}{(3y)^2}} = \sqrt[3]{\frac{ 9x^2y^2 }{ (3y)^3 }} = \frac{\sqrt[3]{9x^2y^2}}{3y} \]

OpenStudy (anonymous):

The previous question has to be simplified because you can't have the square root, cubed root, etc. .. of any number as the denominator.

OpenStudy (anonymous):

Rationalize the denominator.

OpenStudy (ipwnbunnies):

^^^ I guess I didn't understand the problem lol.

OpenStudy (anonymous):

@wio now I understand. Thank you so much!
