And let me just make it clear. This u I could have written in white if I wanted the same color, and this du is the same du right over here. So what is the antiderivative of u to the 1 1⁄2 power? Well, we increment u's power by one. So this is going to be equal to, and let me not forget this 1 7th out front. So it's going to be 1 7th times, 1 7th times, if we increment the power here, it's going to be u to the 3 1⁄2. 1 1⁄2 plus one is 1 1⁄2 or 3 1⁄2.
