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 Examples on Natural Log Calculator

Example 1:

Find the natural logarithm value of log_e⁴ and verify it using the online natural log calculator.

Solution:

Given: Argument value = 4

log_e^a = x ⇔ e^x =a

log_e⁴ ⇔ e^x = 4

x = 1.3863

Therefore, the natural logarithm value of log_e⁴ is 1.3863

Example 2:

Find the natural logarithm value of log_e⁷ and verify it using the online natural log calculator.

Solution:

Given: Argument value = 7

log_e^a = x ⇔ e^x =a

log_e⁷ ⇔ e^x = 7

x = 1.94591

Therefore, the natural logarithm value of log_e⁷ is 1.94591

Example 3:

Find the natural logarithm value of log_e¹² and verify it using the online natural log calculator.

Solution:

Given: Argument value = 4

log_e^a = x ⇔ e^x =a

log_e¹² ⇔ e^x = 12

x = 2.48491

Therefore, the natural logarithm value of log_e¹² is 2.48491

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

• log_e²⁵
• log_e⁴⁵
