Let's take the derivative with respect to x of x to the n plus 1th power over n plus 1 plus some constant c. And we're going to assume here, because we want this expression to be defined, we're going to assume that n does not equal negative 1. If it equaled negative 1, we'd be dividing by 0, and we haven't defined what that means. So let's take the derivative here. So this is going to be equal to the derivative of x to the n plus 1 over n plus 1. We can just use the power rule over here. So our exponent is n plus 1. We can bring it out front.
