Logarithm Definition

In mathematics, logarithm is the inverse operation of exponentiation. That is, we call logarithm of a number the exponent to which another value (the base) must be raised to produce this number. For example, the logarithm of 100 in base 10 is 2, because 102 = 100. Therefore, we have the following definition:

The development of logarithms arose from the need to simplify some mathematical calculations.

Consequences of the definition

By the definition of logarithm, we can observe some consequences, which are as follows:
