When you take the cube root of a negative number, is the sign of the cube root positive (+) or negative (–)?
When you take the cube root of a negative number, the sign of the cube root depends on whether the exponent of the root is an odd number or an even number.
In the case of a cube root (∛), since the exponent is 3 (an odd number), the cube root of a negative number will retain its negative sign. Therefore, the cube root of -125 is -5.
