Here's a definition which might help you: log[sub:2n63nyhx]b[/sub:2n63nyhx] n = a MEANS this: b[sup:2n63nyhx]a[/sup:2n63nyhx] = n Now, see what that gives you when you apply it to YOUR problem: log[sub:2n63nyhx]5[/sub:2n63nyhx] (5x - 1) = 1 5[sup:2n63nyhx]1[/sup:2n63nyhx] = (5x - 1) Does that give you an equation you can solve for x? And does the value you get for x CHECK?
