On one level the answer is you don't since {(-1)^3,(1/2 + I Sqrt[3]/2)^3,(1/2 - I Sqrt[3]/2)^3}//Simplify gives {-1, -1, -1} But if you want to force Mathematica to get a real cube root of a negative number, load the package Miscellaneous`RealOnly` -- To reply via email subtract one hundred and four
