rules of logs

rules of logs Logarithm definition When b is raised to the power of y is equal x b y x Then the base b logarithm of x is equal to y log b x y For example when 2 4 16 Then log 2 16 4 Logarithm as inverse function of exponential function The logarithmic function y log b x is the inverse function of the exponential function x by

In this article we are going to learn the definition of logarithms two types of logarithms such as common logarithm and natural logarithm and different properties of logarithms with many solved examples Table of contents Log rules are rules that are used to operate logarithms Since logarithm is just the other way of writing an exponent we use the rules of exponents to derive the logarithm rules There are mainly 4 important log rules which are stated as follows product rule log b mn log b m log b n quotient rule log b m n log b m log b n power

There are a number of logarithm rules properties and identities that can be used when working with logarithms They can be particularly useful for manipulating and solving algebraic expressions or equations Three basic logarithm rules are the product quotient and power rules Revise what logarithms are and how to use the log buttons on a scientific calculator as part of Higher Maths

The basic laws of logs Product addition Law log a m log b n log a mn Quotient Law log a m log b n log a frac m n Power Law log a x b b log a x Change of Law log a x frac log b x log b a The change of law formula is in the formula booklet you are given in the exam 1 Product Rule Multiplication inside the log can be turned into addition outside the log and vice versa 2 Quotient Rule Division inside the log can be turned into subtraction outside the log and vice versa

The rules of logs are used to simplify a logarithm expand a logarithm or compress a group of logarithms into a single logarithm Here are the rules or properties of logs If you want to see how all these rules are derived click here Let us see each of these rules one by one here Log 1 The value of log 1 irrespective of the base is 0 Study the proofs of the logarithm properties the product rule the quotient rule and the power rule In this lesson we will prove three logarithm properties the product rule the quotient rule and the power rule Before we begin let s recall a useful fact that will help us along the way log b
