Nth Root Calculator
Find square roots, cube roots, and any other root.
How it works
The nth root of a number is the value that gives the number when multiplied by itself n times. Even roots of negative numbers are not real, so they show a dash. Odd roots of negatives work, such as the cube root of −27 = −3. Example: with the default values, root comes to 4.
