Actually the solution is to redefine Power function in this way: Unprotect[Power] Power[x_?Negative, Rational[p_, q_?OddQ]] := -(-x)^(p/q) Protect[Power] This is the answer from Technical Support Wolfram Research, Inc. As you see it is not quite RFTM FAQ-related question as you think at University of Massachusetts, dear Murray. And yes - I have got a HP PC with working F1-key. And yes - I had searched. And I found nearly nothing - some trivial "problems" from texbooks on a very very elementary level. And yes - I like use Google. But the Google has nothing about the question. slawek
