Find the nth root of a number and compare the exact root with a decimal approximation.
Last updated: June 2026 | By Patchworkr Team
The nth root of x is the number that, when raised to the nth power, gives x. For example, the cube root of 27 is 3 because 3^3 = 27.
The cube root of 27 is 3.
Yes, but only when the root is odd. Even roots of negative numbers are not real.
No. The calculator expects a whole-number root.
This tool is focused on numeric nth roots rather than radical simplification.
The calculator rejects it because the root must be nonzero.
