Question 892982

How would I solve, step by step, the problem "5th root 64x^12y^20"?*

*I have no idea how to write the 5th root on this so I wrote it out to specify.
<pre>
{{{root (5, 64x^12y^20)}}}
{{{root (5, 2^5 * 2 * x^10 * x^2 * y^20)}}}
{{{root (5, 2^5 * x^10 * y^20 * 2 * x^2)}}}
{{{root (5, 2^5)}}} * {{{root (5, x^10)}}} * {{{root (5, y^20)}}} * {{{root (5, 2x^2)}}}
{{{2x^2y^4 * root(5, 2x^2)}}}
