Now what about this, natural log of 2? Natural log of 2 is going to be some fraction. It's going to be more than 1 half. And since it's more than 1 half, this whole thing is going to be more than 4, which means this whole thing is going to be positive. So this is negative, this is negative, this is positive. And these are our only candidates for our maximum value. So I would go with this one.
