Homework Statement
Simplify: ##\sqrt{\frac{6}{81y^6}}##
The Attempt at a Solution
If it was just ##\sqrt{\frac{6}{81y}}## I can just say ##\frac{\sqrt{6}}{9\sqrt{y}}## but the power 6 is throwing me off.
Just a couple more to save me making more topics. ##\sqrt{\frac{a^5}{2}}## can't be simplified?
And... ##\sqrt[4]{\frac{2a^8}{b^2c^3}}## I know I need to multiply it by something but I just can't see it.
Thank you.
