What Is a Logarithm?
A logarithm answers one simple question:
“To what power must the base be raised to produce a given number?”
For example:
If
10ยฒ = 100
then
logโโ(100) = 2
This relationship makes logarithms an essential concept in higher mathematics.
Types of Logarithms
Common Logarithm
Uses base 10 and is commonly written as:
log(x)
It is frequently used in science and engineering.
Natural Logarithm
Uses Euler’s number (e โ 2.71828) as the base.
It is written as:
ln(x)
Natural logarithms are widely used in calculus, economics, probability, and exponential growth calculations.
Logarithm with Any Base
Some problems require custom bases such as:
- Base 2
- Base 5
- Base 8
- Base 16
This calculator allows you to calculate logarithms using different bases.
How to Use the Log Calculator
Using the calculator is simple:
- Enter the number.
- Select or enter the base.
- Click the calculate button.
