When t is equal to five, you get 5 6ths times e to the 6 5ths times five is e to the 6th minus five squared, so minus 25, and so from that, I want to subtract. When we evaluate it at two, we get 5 6ths e to the 6 5ths times two is the same thing as 12 5ths, or we could say that's 2.4, 2.4 minus four. Two squared is four, and so what do we get? Well, there's a couple of ways that we could do this. So we could write this as, let me write it this way. We could write this so we have a 5 6ths and a 5 6ths, so we could write this as 5 6ths times e to the 6th minus e to the 2.4 minus, because we distribute that negative sign, e to the 2.4, e to the 2.4 power, and then we have minus 25. Let me just send another color to keep track of it.
