So let's rewrite this. And actually, what I'm going to do is let's just focus on the indefinite integral first, see if we can figure that out, and then we can apply, and then we can evaluate the definite ones. So let's just think about this. Let's think about the indefinite integral of x squared times two to the x to the third power dx. I really want to find the antiderivative of this. Well, this is going to be the exact same thing as the integral of, so I'll write my x squared still, but instead of two to the x to the third, I'm going to write all of this business. Let me just copy and paste that.
