logarithm A logarithm is defined as the power to which a number must be raised to get some other values It is the most convenient way to express large numbers A logarithm has various important properties that prove multiplication and division of logarithms can also be written in the form of logarithm of addition and subtraction
Common Logarithms Base 10 Sometimes a logarithm is written without a base like this log 100 This usually means that the base is really 10 It is called a common logarithm Engineers love to use it On a calculator it is the log button Logarithm the exponent or power to which a base must be raised to yield a given number Expressed mathematically x is the logarithm of n to the base b if bx n in which case one writes x log b n For example 2 3 8 therefore 3 is the logarithm of 8 to base 2 or 3 log 2 8 In the same fashion since 10 2 100 then 2 log 10 100

You will learn what logarithms are and evaluate some basic logarithms This will prepare you for future work with logarithm expressions and functions Solving Exponential Equations Logarithms provide a way to solve equations involving exponents When you have an equation of the form a x b taking the logarithm of both sides allows you to solve for x This is particularly useful when dealing with exponential growth or decay problems
A logarithm is defined using an exponent b x a log b a x Here log stands for logarithm The right side part of the arrow is read to be Logarithm of a to the base b is equal to x A very simple way to remember this is base stays as the base in both forms and base doesn t stay with the exponent in log form A logarithm is the inverse of the exponential function Specifically a logarithm is the power to which a number the base must be raised to produce a given number For example log 2 64 6 because 2 6 64 In general we have the following definition z is the base x logarithm of y if and only if x z y In

About this unit Logarithms are the inverses of exponents They allow us to solve challenging exponential equations and they are a good excuse to dive deeper into the relationship between a function and its inverse Key Takeaways Given any base b 0 and b 1 we can say that logb1 0 logbb 1 log1 bb 1 and that logb 1 b 1 The inverse properties of the logarithm are logbbx x and blogbx x where x 0 The product property of the logarithm allows us to write a product as a sum logb xy logbx logby
