Just to be clear. This right over here is this right over here. And we're multiplying. And we're done. We have just applied the power rule. So just to review, it's the derivative of the outer function with respect to the inner. So instead of having 1 half x to the negative 1 half, it's 1 half g of x to the negative 1 half times the derivative of the inner function with respect to x times the derivative of g with respect to x, which is right over there.
