Let me do this in this green color. So times the derivative of e to the x with respect to x is just e to the x. So that right over there is the derivative of e to the x with respect to x. And so we're essentially done. We just have to substitute what we found using the chain rule back into our original expression. The derivative of this business up here is going to be equal to, let me just copy and paste everything just to make everything nice and clean. So copy and paste.
