What Does Logarithm (LN) Mean?

A logarithm (LN) is a concept in mathematics that denotes the number of times a number has to be multiplied by itself in order to arrive at a specified value. In mathematical terms, a logarithm of a number is the exponent that is used to raise another number, the base, in order to arrive at that number.

Logarithm is the reverse of the operation of exponentiation, which is raising a number according to a power. In exponentiation, a final value is determined after raising a base value with its exponent, while in logarithm, the final value and base are already known and the exponent is the value in question.
