Witryna10 lis 2024 · Remember that "the logarithm is the exponent'' and you will see that a = e ln a. Then a x = ( e ln a) x = e x ln a, and we can compute the derivative using the chain rule: (3.6.5) d d x a x = d d x ( e ln a) x = d d x e x ln a = ( ln a) e x ln a = ( ln a) a x. The constant is simply ln a.
