# Laws of Logarithms: ln(x/y) = ln(x) - ln(y)

in hive-196037 •  6 days ago  (edited) In this video I go over the logarithm law ln(x/y) = ln(x) - ln(y) and prove it using the previous log law which I proved in my earlier video which is ln(xy) = ln(x) = ln(y). Note that in this video I prove this law strictly using integrals and derivatives and not on the old definition of logarithms as the inverse of exponential functions like I showed in my properties of logarithms video.

I don't always prove logarithm laws but when I do I make sure to use previous log laws that I've proven earlier ;)
