And the logform basically states that our log of our base x in parentheses is our result y and this equals our exponent. So why is this useful? Well let's see. If we know our base and we know our y, the result and we don't know our e, there's nothing we can do in this form to solve this problem. But what we can do is simply convert this guy to log form and we get log of x, which is what we know. In parentheses is our y, which is also what we know.
