## How to Find Natural Log Calculator?

A logarithm is defined using an exponent = b^{x} = a ⇔ log_{b}^{a} = x**, **where b is base, a is an argument and, x is a real number

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)

A natural logarithm is defined as the logarithms to the base e. It is represented by **log _{e}** and also can be written as

**ln.**

e^{x} =a ⇒ log_{e}^{a} = x ⇒ ln a = x

Where a is argument value and take e = 2.71828

**Solved Example:**

Find the natural logarithm value of log_{e}^{4}

**Solution:**

Given: Argument value = 4

log_{e}^{a} = x ⇔ e^{x} =a

log_{e}^{4 }⇔ e^{x} = 4

x = 1.3863

Therefore, the natural logarithm value of log_{e}^{4 }is 1.3863

Similarly, you can try the calculator to find the natural logarithm value of

- log
_{e}^{25} - log
_{e}^{45}
