...the logarithm, you know this property. Now suppose that I take the logarithm of the product. Since the log of a product is equal to the sum of the logs, we have log 110-7)= 2 logo - 1). pSx P p*x P But log (1 — 1 I p) is approximately equal to — 1...

...very little Many important facts about logarithms can be proved starting with the single fact that the log of a product is equal to the sum of the logs. To be specific, we say log(Aß) = log(A) + log(ß). Here, and below, it is assumed that A and B are...
