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. We're going to take our exponent, multiply it by our coefficient out front. Actually, let me write that out. So that's going to be, let me finish this equal sign.
