# Logarithm

Learn logarithms easily from basics to advanced level for both beginners and advanced learners.

A mathematical approach of calculating the number of multiplying factors when a number is split as number of multiplying factors on the basis of another number is called logarithm.

## Introduction

Knowledge on exponents is required to study the logarithms.

The concept of exponents is used to express any number as another number raised to the power of number of multiplying factors.

$2^3 = 2 \times 2 \times 2 = 8$

Logarithm is used for inverse operation and it determines the number of multiplying factors when a number is split on the basis of another number.

$\log_{2}{8} = 3$
