We know that one over x to the n is the same thing as x to the negative n. So I just rewrote it, and now this might be ringing a bell of how the power rule might be useful. And then we have minus, well, one over x squared, that is the same thing as x to the negative two. And so this, if we're gonna take the derivative of both sides of this, let's do that. Derivative with respect to x, dx. We're gonna do that on the left-hand side. We're also gonna do it on the right-hand side. Well, on the left-hand side, the derivative with respect to x of g of x, we can write that as g prime of x is going to be equal to, well, the derivative of this first, what we have right here written in green, this is going to be, we're just going to apply the power rule.
