What is Antilog?

Antilog is an inverse function of the logarithm so we can find the antilog (antilogarithm) with the inverse process of finding the logarithm any number.

Suppose that y is the logarithm of a number x with a given base b, and then b^y is the antilogarithm (antilog) of x to the base b.

If log_b x = y then Antilog = b^y

Antilog Formula

The equation to find the antilog is given below:

X = Antilog_b (log_b x)

X = Antilog_b y

X = b^y

In this equation

X = Antilog value

b= base of the log

Y= log value                            

How to calculate Antilog?

For the calculation antilog of any number X, you need to raise the logarithm base b (usually 10, sometimes), to the power of Y: x = log_b-1(y) = b^y

Since log and antilog are inverse functions, then this means that x = by = blog bx, and y = logbx = logb(by).

To calculate the Antilog let’s take an example:

• Example#01:

Find the antilog for base 10 and the log value 4.

Solution

Step 1: Identify the values from the given problem.

Base (b) = 10

Log value y = 4

Step 2: Use in antilog expression.

Antilog = b^y

Antilog = 10⁴

Antilog = 10 x 10 x 10 x 10

Antilog = 10000

• Example#02:

Find the antilog for base 2 and the log value 7.

Solution

Step 1: Identify the values from the given problem.

Base (b) = 2

Log value y = 7

Step 2: Use in antilog expression.

Antilog = b^y

Antilog = 2⁷

Antilog = 2 x 2 x 2 x 2 x 2 x 2 x 2

Antilog = 128
