You can put this solution on YOUR website!
%28root%2813%2C+9x%5E2y%29%29%5E3
In general


a%5E%28p%2Fq%29+=+root%28q%2C+a%5Ep%29+=+%28root%28q%2C+a%29%29%5Ep

Your expression matches the pattern on the far right of the above. So your expression will be:


%289x%5E2y%29%5E%283%2F13%29
br>
The rational exponent will not reduce so we are finished.
