Comment #5 on issue 216 by ronan.l...@gmail.com: (-1)**Rational(1,3) could be automatically rewritten using I http://code.google.com/p/sympy/issues/detail?id=216
This is still XFAILing, but I don't think that this should be evaluated automatically. On the other hand, im((-1)**Rational(1,3)) should return Rational(1,2)*3**Rational(1,2) and applying some function (such as simplify or expand or ...) should return the expanded form. There is also a problem in the inconsistency between the square root and n-th roots, n>2. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
