So it's going to be negative, we'll bring that negative out front, so we're essentially just gonna use the power rule here. Negative two x minus five to the negative two. And then we multiply that times the derivative of, times the derivative of the inside function. So the inside function's derivative, the derivative of two x is two, derivative of negative five is zero, so it's gonna be times two. And of course you can simplify it, so it's negative two times all of this business. Let me do one more example here, just to hit the point home. And once again, there isn't a must way, there isn't a way that you have to do this, but just let you appreciate that there's multiple ways to approach these types of derivatives.
