Now what is this going to be equal to? Well, this is going to be equal to, this is just algebra at this point, one over, we have our two, and square root of x times square root of x is just x. So it just simplifies to one over two x. So hopefully this made sense, and I intentionally diagrammed it out so you start to get that muscle in your brain going of recognizing the composite functions, and then making a little bit more sense of some of these expressions of the chain rule that you might see in your calculus class or in your calculus textbook. But as you get more practice, you'll be able to do it essentially without having to write out all of this. You'll say, okay, look, I have a composition. This is the natural log of the square root of x.
