Laws of Logarithms: ln(x*y) = ln(x) + ln(y)

In this video I go over some laws of logarithms and prove the law ln(x*y) = ln(x) + ln(y). In my earlier videos on logs and their properties I proved this same law but using the definition of logarithms as the inverse of the exponential function. In this video, however, I show how to prove logarithm laws using integrals and derivatives like I explained in my last video.
