WebbTo get only real roots one can use for example : Reduce [x^3 + 8 == 0, x, Reals] or Solve [x^3 + 8 == 0, x, Reals]. They do almost the same, but their outputs are a bit different, respectively : in the boolean form and in the form of rules. As a more appropriate example of what you want to do I could choose this one : (-3)^ (1/7).
