It looks like the equation is
Right away, we notice that any solution to this equation must be positive, so <em>x</em> > 0.
For any base <em>b</em>, we have , so we can simplify this to
Next, , so that
Next, , so that
For <em>x</em> ≠ 0, we have , so that
Take the antilogarithm of both sides:
Solve for <em>x</em> :
