### 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= loga x if and only if x = ay
Then the logarithmic function is given by
f(x) = loga 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)
