In[12] := Simplify[(a^2)^(3/2), Element[a, Reals]] Out[12] = Abs[a]^3 In[10] := Simplify[(a^2)^(3/2), Element[a, Reals] && a >= 0] Out[10] = a^3 The correct result is a^3 only when a is real and a>=0 jean pellegri "Cole Turner" <REMOVEcole.tuner at liwest.at> a écrit dans le message de news:cl4tg0$8g7$1 at smc.vnet.net... > if I enter: > > FullSimplify [ (a^2)^(3/2) ] > > (in correct MATHEMATICA syntax, the program does not yield the correct > result, a^3 ... > > why is that? > > thanks! > -- > Johnny: [plugging back in the runway lights] > "Just kidding." > ('Airplane!', 1980) >
