Logarithms are the mathematical function that is used to represent the number (y) to which a base integer (a) is raised in order to get the number x: x = ay; where y = loga(x). Most of you are familiar with the standard base-10 logarithm: y = log10(x); where x = 10y.
27 Δεκ 2021 · Logarithms are used in many different calculations. There is an overview on logarithms in Chapter ? that explains how logs work. In this section we are going to focus on how to use them in sheets.
27 Μαρ 2023 · A logarithm is simply the number of times we need to multiply one number together to make another number i.e. it is the power to which a number must be raised to get another number. Logarithms allow us to deal with extremely large or extremely small numbers without getting our heads in a spin.
A logarithm is a mathematical function that describes the power to which a fixed number, called the base, must be raised to get another number. Logarithms are closely related to the concepts of pH and pOH, which are used to measure the acidity or basicity of a solution.
30 Απρ 2009 · Definition. If three numbers represented as a, b and c obey the relationship: a = bc (i) then we can also say that: c = log b a (ii) The function log b is the logarithm to base b. Although logarithms can be defined to any base, we will consider here only logarithms to base 10 because these are conceptually easier to understand.

Logarithms and Exponentials. The common logarithm of a number (log) is the power to which 10 must be raised to equal that number. For example, the common logarithm of 100 is 2, because 10 must be raised to the second power to equal 100. Additional examples follow.
