Question

Can you find the cube root of a negative number? If so, it is positive or negative? Explain your reasoning.

Answer 1

It will always be negative, because negative times negative times negative is positive.  for example,  -1 x -1 x -1 = 1 x -1  = -1
So when finding cube root you find the number which can multiply itself three times to get the number.
Cube root of -8 is -2
because -2 x -2 x -2
             =4 x -2
             =-8
Thus all cube root of negative numbers are negative because negative times  negative times negative is negative.
