And we want to find our e. So now we have this entire guy. We don't count this guy. So now what we can do is simply plug this guy to the calculator, get an answer, and that's our e. Now suppose we were in the opposite situation. Suppose we had our log x our base and we had our exponent and we didn't have our y. Well now we don't have this entire thing. So we can plug this into our calculator.
