In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed . In its simplest form, a logarithm the question: How many of one number do we multiply to get another number? You will learn what logarithms are, and evaluate some basic logarithms. This will prepare you for future work with logarithm expressions and functions.

In this section we now need to move into logarithm functions.

This can be a tricky function to graph right away. There is going to be some different notation that . A logarithm is the opposite of a power. In other words, if we take a logarithm of a number, we undo an exponentiation. Sal explains what logarithms are and gives a few examples of finding logarithms.

Two kinds of logarithms are often used in chemistry: common (or Briggian) logarithms and natural (or Napierian) logarithms. The power to which a base of 10 . Although a logarithm may be defined with any base, the logs most often encountered are the logarithm to the base which is called the common logarithm. Natural logarithm , element-wise. The natural logarithm log is the inverse of the exponential function, so that log(exp(x)) = x.
