I see here a syntax problem. 1. Function name should be "Solve" rather then "SOLVE" 2. use squar brackets for functions, tather then () 3. use == to denote "equal" and not = So, after these corrections Solve[x^4-1==3,x] returns {{x -> -Sqrt[2]}, {x -> (-I)*Sqrt[2]}, {x -> I*Sqrt[2]}, {x -> Sqrt[2]}} yehuda On 5/10/05, Mike <jenningsmca_REMOVETHIS at hotmail.com> wrote: > I have tried multiple problems (simple ones albiet) to solve while in > ALG mode. > SOLVE(x^4 - 1 = 3, x) > but this provides no result.
