The equation: x^3 = -8 will have how many solutions for x?
a. One solution: x = -8/3 since the inverse operation is to divide by 3.
b. Two solutions: x = -8/3 and x = 8/3, since x^3 equations always have 2 solutions.
c. Two solutions: x = 2 and x = 2, since 2^3 = 8 and (-2)^3 = 8.
d. One solution: x = -2 since (-2)^3 = -8 .
