Use this calculator to find the cube root of positive or negative numbers. Given a number *n*, the cube root of *n* is a number *a* such that *a ^{3} = n*. Cube roots is a specialized form of our common roots calculator also know as a radicals calculator.

- The 3rd root of 64, or 64 radical 3, or the cube root of 64 is written as
^{3}√ 64 = 4. - The 3rd root of -64, or -64 radical 3, or the cube root of -64 is written as
^{3}√-64 = -4. - The cube root of 8 is written as
^{3}√ 8 = 2 - The cube root of 10 is written as
^{3}√ 10 = 2.154435

The cube root of *n* is the same as *n* raised to the 1/3 power. Written as ^{3}√ *n* as *n ^{1/3}*. The common definition of the cube root of a negative number is that

(-n)

- The cube root of -27 is written as
^{3}√-27 = -3. - The cube root of -8 is written as
^{3}√-8 = -2. - The cube root of -64 is written as
^{3}√-64 = -4.
