Well, let's first take the first derivative of y with respect to x. And to do that, let's just remind ourselves that we just have to apply the power rule here. And we can just remind ourselves, based on the fact that y is equal to six x to the negative two. So let's take the derivative of both sides of this with respect to x. So with respect to x, I'm gonna do that. And so on the left-hand side, I'm gonna have dy dx is equal to, now on the right-hand side, take our negative two, multiply it times the six, it's gonna get negative 12x to the, negative two minus one is x to the negative three. And actually, let me give myself a little bit more space here so this is negative 12x to the negative three.
