Definition: Logarithm is a mathematical operation that involves finding the power to which a base (or sometimes the number itself) must be raised in order to get a given number. It is often used to perform calculations involving exponential functions, but it can also be applied to other types of quantities where the relationship between two numbers is exponential. For example: - In mathematics, logarithms are used to calculate the exponent of a base that gives a certain result when multiplied by itself. - In chemistry, logarithms
