Logarithms

Abstract

A logarithm is a variation in the form of an exponential number. The two most commonly used logarithms are Base 10 and Base 'e'. Log (A) is read: Log base 10 of A. Log base 10 (Log10) is referred to as the “Common” logs, whereas Log base e (Log e ) is referred to as the “Natural” logs and uses the abbreviation (Ln). Unless otherwise indicated the term Log (x) is always understood to be base 10 or Log10(x)
