So really think about this. Don't just accept this as a leap of faith. It should make sense to you, and it just comes out of really what a logarithm is. And so we can replace a with this whole expression here. We can, if a is the same thing as e to the natural log of a, well, then this is going to be, then this is going to be equal to the derivative with respect to x of e, e to the natural log, I keep writing la, to the natural log of a, and then we're gonna raise that to the xth power. We're gonna raise that to the xth power. And now this, just using our exponent properties, this is going to be equal to the derivative with respect to x of, and I'll just keep color coding it.
