I took the derivative of the outside with respect to the inside, and I'm gonna multiply that times the derivative of the inside. So what's the derivative of u of x? u prime of x. Let's see, we're just gonna use the power rule a bunch of times. It's going to be three x squared plus two times four is eight. X to the two minus one is just one power, first power. So that's just, I can just write that as eight x.
