So e raised to this power is the same thing as e raised to that power. So we have e to the natural log of W minus 300 is going to be equal to e to the t over 25 plus the natural log of 1,100. Let me take this, let me actually, just to get the real estate, let me delete that. All right, now I can keep working right below that. And so e to the natural log of something is just going to be equal to that something. The natural log is what power do I have to raise e to to get this thing? Well, I'm raising e to that power, so I'm going to get this thing.
