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]}}
