How does antilog calculator work?

This inverse log calculator is very easy to use. You will need to;

  1. Enter the number (log value).
  2. Enter the antilog base.
  3. Click “Calculate” or press enter.

What is Antilog?

Anti means ‘Inverse’. It is the process of raising the log to its base. Since the log is the inverse of exponents, and antilog is the inverse of the log so eventually, antilog is equal to exponent.

In other words, it is the method of getting to the original value. For example:

                                  Log (p) = q    ;    log-1(q) = p 

Keep in mind that the base of antilog cannot be negative. Also, for a question where no base is provided, base 10 is used to find the antilog. It is because;   

                                            log(x) = log(10)

Antilog formula

As explained before, the inverse logarithm is actually exponential. So it has the same expression as exponents. 

                                                          by

Where ‘b’ is the base and ‘y’ is the log value. To identify these from log expression look below:

                                                      X = logb-1(y) = by

How to find antilog?

Example:

Find the antilog for the base 8 and the log value 3.

Solution:

Step 1: Identify the values.

Base (b)  = 8

Log value = 3

Step 2: Use in antilog expression.

= by

= 83

= 512
