how do log functions work Logarithms made it easy for people to carry out otherwise difficult operations eg find the value of 4th root of 24 we can simply take log 24 and divide by 4 The antilog of the resultant figure will give us the answer
Introduction to Logarithms In its simplest form a logarithm answers the question How many of one number multiply together to make another number Example How many 2 s multiply together to make 8 Answer 2 2 2 8 so we had to multiply 3 of the 2 s to get 8 So the logarithm is 3 How to Write it We write it like this log2 8 3 In mathematics the logarithm is the inverse function to exponentiation That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x For example since 1000 103 the logarithm base of 1000 is

The logarithmic function y log b x is the inverse function of the exponential function x b y So if we calculate the exponential function of the logarithm of x x 0 f f 1 x b log b x x Or if we calculate the logarithm of the exponential function of x f 1 f x log b b x x Natural logarithm ln Natural logarithm In this section we will introduce logarithm functions We give the basic properties and graphs of logarithm functions In addition we discuss how to evaluate some basic logarithms including the use of the change of base formula We will also discuss the common logarithm log x and the natural logarithm ln x
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 Discover the link between exponential function b M and log M N in this article about Logarithms Explained Understanding this basic idea helps us solve algebra problems that require switching between logarithmic and exponential forms

Logarithms are the inverse of exponential functions they allow us to undo exponential functions and solve for the exponent They are also commonly used to express quantities that vary widely in size Learn the eight 8 log rules or laws to help you evaluate expand condense and solve logarithmic equations Try out the log rules practice problems for an even better understanding
Logarithmic functions with definitions of the form f x log b x have a domain consisting of positive real numbers 0 and a range consisting of all real numbers The y axis or x 0 is a vertical asymptote and Working with Exponents and Logarithms What is an Exponent What is a Logarithm A Logarithm goes the other way It asks the question what exponent produced this And answers it like this In that example The Exponent takes 2 and 3 and gives 8 2 used 3 times in a multiplication makes 8
