One example would be x to the power of 1/3
which we would write as x^(1/3) for shorthand
It converts to "cube root of x".
----------------
The general rule is
[tex]x^{1/n} = \sqrt[n]{x}[/tex]
if the font is too small, then the formula reads x^(1/n) is equal to square root x, with a small little n just above and to the left of the square root. This is known as the nth root of x.
Based on that general formula, we can say something like
[tex]x^{1/4} = \sqrt[4]{x}[/tex]
(x to the 1/4th power is equal to fourth root of x)
note: you can replace x with any algebraic expression you want
