And here we're going to have to use a little bit of the chain rule. The derivative of the outside, which we could kind of use something to the negative 1 power with respect to that something, is going to be negative 1 times that something, which in this case is g of x, to the negative 2 power. And then we have to take the derivative of the inside function with respect to x, which is just g prime of x. And there you have it. We have found the derivative of this using the product rule and the chain rule. Now, this is not the form that you might see when people are talking about the quotient rule in your bath book. So let's see if we can simplify this a little bit.
