### What is Meant by Logarithm?

In Mathematics, the logarithm is considered as a convenient method to express the large numbers. The logarithm is defined as a power to which some number is raised in order to get some other numbers. The logarithmic function is generally defined as follows:

For x > 0 , a > 0, and a≠1,

y= log_{a} x if and only if x = a^{y}

Then the logarithmic function is given by

f(x) = log_{a} x

There are two different types of logarithmic functions. They are:

1. Common Logarithmic Function (whose base is 10)

2. Natural Logarithmic Function (Whose base is e)
