So this is x to the negative four power. So two times negative three x to the negative four, or we could have also written that as negative six x to the negative four power, and then minus, well, we're going to do the same thing again right over here. We take this negative two, multiply it times the coefficient that's implicitly here. You could say there's a one there, so negative two times one. So you have the negative two there, and then you have the x to the, well, what's negative two minus one? Well, that's negative three to the negative three power. And so we can rewrite all of this business as the derivative g prime of x is equal to negative six, negative six x to the negative fourth, and now we're subtracting a negative, so we could just write this as plus two x to the negative three.
