But if I try in SageMath to do
(-1)^(1/3)
SageMath return (-1)^(1/3). When I try
(-1)^(1/3).n()
SageMath gives me numerical approximation of the one root (not real)...
How I can get all variants of complex cube-root without numerical approximation?
Thanks! P.S. Sorry for poor English...avi9526Thu, 25 Apr 2013 15:31:30 +0200https://ask.sagemath.org/question/10063/
