Logarithm - Wikipedia In mathematics, the logarithm of a number is the exponent by which another fixed value, the base, must be raised to produce that number For example, the logarithm of 1000 to base 10 is 3, because 1000 is 10 to the 3 rd power: 1000 = 103 = 10 × 10 × 10
Introduction to Logarithms - Math is Fun 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"
Intro to Logarithms (article) - Khan Academy Learn about the properties of logarithms that help us rewrite logarithmic expressions, and about the change of base rule that allows us to evaluate any logarithm we want using the calculator
Logarithm (Logs) - Examples | Natural Log and Common Log To understand logarithms, it is sufficient to know that a logarithmic equation is just another way of writing an exponential equation Logarithm and exponent are inverse forms of each other

What is a Logarithm? Definition and Examples What is a logarithm in easy terms? Keep in mind that whenever you are looking for the logarithm, you are looking for an exponent, or the number that tells how many times the base is multiplied For example, what is the logarithm of the expression log 5 25? 2 is the logarithm of the expression log 5 25 Why?
