well.. no one gave the most accurate answer but I think the best one is Eulercrosser ... so I'll let it opedned for more time

There are actually 3 cube roots of 8 (only one is real):
the three cube roots (or solutions to x*3=8) are:
2, 2*exp(2πi/3), and 2*exp(4πi/3)

x = 2

That would be 2.

Suppose x^3=8. Then x^3-8=0, which is a difference of cubes and factors into (x-2)(x^2+2x+4). So if x is a solution, then either x=2 or x^2+2x+4=0. The latter equation can be solved with the quadratic equation, which will give you the two other possibilities.
