what squared root to 4 is 81?
The 4th root of 81 is 3.
3*3*3*3=81, so the 4th root of 81 is 3.
That would be correct if Guest asked "what is the fourth root of 81."
However, he/she asked what squared root to 4 is 81.
Wouldn't that technically be 81 * 81 * 81 * 81 = 43,046721?
Maybe Guest meant "what squared to 4 is 81."
