Your question is not clear.
Maybe you meant a fourth root, and wanted to know how to write root%284%2C18%29 as a power with a rational exponent.
In that case, root%284%2C18%29=18%5E%281%2F4%29 , with a 1%2F4 as the exponent.
If it really was a square root, maybe the problem was %28sqrt%2818%29%29%5E4

You could solve that using rational exponents too, as in
