Is there a $n-th$an $n^{\text{th}}$ root function in Mathematica?

Is there a way to find $\sqrt[n]{x}$ with MathematicaMathematica beside of x^(1/n) as this is something different, because this is not always the same $$(-1)^{\frac{2}{4}}=i \neq 1= \sqrt[4]{(-1)^2}$$ In the help I only found Sqrt[x] which is the squareroot and CubeRoot[x] for the cubic root.
Is there a reason that there aren't $n$-th roots implemented? (Assuming they really don't exist and I am not to stupid to find them).
