Introduction
Logarithms are the opposite phenomena of exponential like subtraction is the inverse of addition process, and division is the opposite phenomena of multiplication. Logs “undo” exponential.
There are a number of rules known as the laws of logarithms. These allow expressions involving
logarithms to be rewritten in a variety of different ways. The laws apply to logarithms of any base
but the same base must be used throughout a calculation
First Law
log A + log B = log AB
Second Law
log A − log B = log (A/B)
Third Law log An = n log A
log 1 = 0, logmM = 1
