Question 1

What is an antilog?

Accepted Answer

An antilog (antilogarithm) is the inverse of a logarithm. If log base b of x equals y, then the antilog of y base b is x. In other words antilog_b(y) = b^y. For base 10, antilog(y) = 10^y.

Question 2

How do I calculate the antilog of a number?

Accepted Answer

Raise the base to the power of your log value. For common log (base 10): antilog(2) = 10^2 = 100. For natural log: antilog of ln is e^x, so the antilog of 2 with base e is e^2 = 7.389. For base 2: 2^x.

Question 3

What is the difference between antilog and exponent?

Accepted Answer

They are the same operation. Antilog is just the older name for raising the base to a power. Antilog base 10 of x equals 10^x, and the inverse of natural log (ln) is the exponential function e^x.

Question 4

How do I find the antilog on a calculator?

Accepted Answer

Use the 10^x key for common log antilogs (base 10), the e^x key for natural log antilogs, or the general y^x / power key with your base. This tool does all three automatically and shows the steps.
