Antilog calculator

Antilog, or antilogarithm, is the reverse process of a logarithm. It helps you find the original number when you know its logarithmic value. In simple terms, if the logarithm of a number is \( x \), the antilog of \( x \) will give the original number.

Formula for Antilog

The antilog formula is straightforward:

\[
y = 10^x
\]

• \( y \): The original number (antilog result).
• \( x \): The logarithm value.

For natural logarithms, where the base is \( e \), the formula becomes:

\[
y = e^x
\]

How to Calculate Antilog

1. Identify the Logarithmic Value: Note the value for which you need to find the antilog.
2. Apply the Formula: Use \( 10^x \) (or \( e^x \) for natural logs).
3. Use a Calculator: Many scientific calculators have a dedicated antilog button.

Example of Antilog Calculation

Let’s calculate the antilog of 2:

\[
y = 10^2 = 100
\]

For a natural log example:

\[
y = e^{1.5} \approx 4.48
\]

Why Use Antilog?

Antilog has applications in:

• Scientific calculations.
• Decibels in acoustics.
• Earthquake magnitudes on the Richter scale.
• Financial growth calculations.
