And I'll give you some hints. All you really need to do is apply the power rule, a little bit of basic exponent properties, and some basic derivative properties to be able to do this. All right, now let's just do this together. And I'll just rewrite it. G of x is equal to this first term here, two over x to the third. Well, that could be rewritten as two times x to the negative three. 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.
