Concerning the recent question about PowerExpand of (-1/t)^(3/2) Sqrt[-t] note that the results depend on how you enter the formula.... PowerExpand[Sqrt[(-1/t)^3] Sqrt[-t]] gives the result -1/t whereas PowerExpand[Sqrt[-1/t]^3 Sqrt[-t] gives the result 1/t apparently typing in (-1/t)^(3/2) Sqrt[-t] in Mathematica corresponds to the second way... jerry blimbaum NSWC Panama City, Fl
