The logs more or less disappear!
A special problem. If it were possible for the bases to be either positive or negative, we might encounter a case involving an absolute value. For now, don't worry about what that is. Why? Because the base "5x" is negative if and only if x is negative.
We know that x cannot be negative because
In this case...
if and only if the bases are equal. That is,
Solve this as
by using factoring.
Finish it off now. There are two solutions.
