Equation with symbolic parameters

Given: F=P(1 + i)^n, solve for i, when F,P,n are symbolic parameters and F>or=0, P>0 & n>or=1 this is not a difficult task and yields i=(F/P)^(1/n) - 1 When entered in Mathematica (Free Form entry) i.e.: = solve F=P*(1 + i)^n, i nothing happens except a "running" status or the restatement in Mathematica language form with unknown attachments. Do you have any suggestions?
