    Yes, you can find the cube root of a negative and it will be a negative number. Think of it like this.

    55 = 25

    -5x-5=25

    BUT

    -5x-5x-5x = - 125

    The cube root of - 125 is - 5.

    This happens because multiplying 2 negatives together gives you a positive, then you multiply that positive number by a negative and get the final result as a negative number!
