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. We already established this is the same thing as two to the x to the third power. Copy and paste it just like that. And then let me just close it with a dx.
