You can put this solution on YOUR website!
Simplify:
sqrt%28x%5E4y%5E3%29
Rewrite this as:
sqrt%28x%2Ax%2Ax%2Ax%2Ay%2Ay%2Ay%29
Now, you can see that x*x or x^2, and y*y or y^2 can be pulled out from beneath the radical, leaving you with:
highlight%28x%5E2y%5E2sqrt%28y%29%29
And you are done.
Good luck,
