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
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
(x to the 1/4th power is equal to fourth root of x)
note: you can replace x with any algebraic expression you want
