This, this is not right. Be very careful that you're not doing that. You do the derivative of the outside function with respect to the inside function, not taking its derivative, and then multiply, don't forget to multiply, times the derivative of the inside function here. So hopefully that helps a little bit. If all of this looks completely foreign to you, I encourage you to watch the whole series of chain rule introductory videos and worked examples we have. This is just a topping on top of that to make sure that you don't fall into these misconceptions of applying the product rule when you really need to be applying the chain rule, or forgetting to do part of the chain rule, multiplying by g prime of x, or evaluating f prime of g prime of x. So hopefully that helps.
