We used that case, but we have to make sure that this x, that we can use this case, that this x is greater than zero. And we might be tempted right when we look at this to say, wait, wait, this looks like a negative number. But we have to remind ourselves that the natural log of three-fourths, since three-fourths is less than e, the natural log of three-fourths is going to be a negative number. It's going to be e to some negative exponent. So since this is negative and this part right over here is negative, so that is also negative. You have a negative times a negative, so this right over here is going to be positive. So this is a positive value right over here.
