And what we're gonna do in this video is leverage the natural log, because we know what the derivative of the natural log is. So this derivative is the same thing as the derivative with respect to x of, well, log base a of x can be rewritten as natural log of x over natural log of a. And now, natural log of a, that's just a number. I could rewrite this, I could rewrite this as, write it this way, one over natural log of a times natural log of x. And what's the derivative of that? Well, we could just take the constant out. One over natural log of a, that's just a number.
