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.
Logarithms 1. Common Logarithm The term “logarithm” comes from combining the two Greek terms logos (“to calculate”) and arithmos (“a number”). Developed by John Napier in 1614, the purpose of a logarithm is to do multiplication and division by basic addition and subtraction.

à Definition of logarithm. To begin, recall that the logarithm base 10 of x is the power to which 10 is raised to equal x, x = 10log10HxL. In the natural logarithm has the base following, logH...L means logarithm base 10. We also will use the natural logarithm.

The exponential and logarithmic functions are important functions in science, engineering and economics. They are particularly useful in modelling mathematically how populations grow or decline.
