If I'm right, you're searching for square, cube or nth root.

sqrt(81); pow(81, 1/2); // square root

pow(27, 1/3); cube root

pow(64, 1/$n); // you'll have to guess this

Addendum: some languages (mine, for example) use the term "radical" for "square root". I guess OP thought it's that simple to translate. LINK
