square root of a = a to the power 1/2
cube root of a = a to the power 1/3
n-th root of a = a raised to the power 1/n, n integer different from 0.
How to use calculator to calculate cube root?
If you do not have a specific (shortcut) key for it you use the key to raise to an arbitrary power [^ ], sometimes shown as [x^y]. The exponent will be 1/3. Do not replace 1/3 by its decimal approximate.
Cube root of 27 is entered as 27 [^ ] (1/3)
