Simplify by taking roots of the numerator and the demoninator. Assume that all expressions under radicals represent positive numbers.

The square root of 243x^6/y^20 to the fifth root.

Here is what I have so far: the square root of 243x^6 to the fifth root divided by the square root of 4^20 to the fifth root.

This is the answer that I got but I'm sure it is wrong.

3x^4 x^2 to the fifth root divided by y^4.
