Log Calculator is a tool created for calculating the values of logarithms in various bases such as e, 10, or others. Here, you need to enter the input for which you want to find the logarithm value and specify the base of the logarithm.

How to Use Log Calculator?

To use Log Calculator you can use the following steps:

Step 1: Enter the number for which you want to find the logarithm into the “Enter Number” input.

Step 2: Enter the base of the logarithm in the “Enter Base” input.

Step 3: Click on “Calculate”.

Step 4: Interpret the result based on your requirements.

Step 5: Repeat the process for additional calculations if necessary.

What is Logarithm?

Logarithm is a mathematical function that determines the exponent or power to which a fixed number, known as the base, must be raised to produce a given number.

In other words, it represents the inverse operation of exponentiation. Logarithms are denoted by the notation “log” followed by a subscript indicating the base of the logarithm.

Logarithm Definition

Logarithm of a number “x” with base “b” is expressed as follows:

log_b(x) = y

Here, “x” is the given number, “b” is the base, and “y” is the exponent or power to which “b” must be raised to obtain “x”.

For example, if we have log₂(8) = 3, it means that 2 raised to the power of 3 equals 8.

Log Table

Log table, short for logarithm table, is a reference tool used in mathematics and various scientific disciplines which helps students and other professional in their logarithmic calculations. Log tables generally list the logarithms of numbers with various bases, such as common logarithms (base 10) or natural logarithms (base e).
