Question 1027178

Hi, I'm having  trouble solving and figuring what to do in this problem: 

*fourth root*81x^6y^8

Thank you.
<pre>There's nothing to solve here. The expression needs to be simplified.
{{{root (4, 81x^6y^8)}}}
{{{root (4, 3^4 * x^4 * x^2 * (y^2)^4)}}}
{{{highlight_green(3xy^2 * root(4, x^2))}}}
