Cube Root Calculator
Find the exact or decimal cube root of any positive or negative number.
Understanding Cube Roots
The cube root of a number x is the number y which, when multiplied by itself three times (y × y × y), equals x.
Negative Cube Roots
Unlike square roots, you can take the cube root of a negative number. Because a negative multiplied by a negative is a positive, and multiplied by a third negative returns to negative, the cube root of -8 is exactly -2.
