Standard Logarithm

A logarithm answers the question:

“To what power must the base be raised to get the given number?”

For example:

$\log_{2}(8)=3$log2​(8)=3

Because:

$2^{3}=8$23=8

Antilogarithm

An antilogarithm is the reverse process of a logarithm.

For example:

$10^{2}=100$102=100

The antilog of 2 with base 10 equals 100.

---

Natural Logarithm

Natural logarithms use Euler’s number (e) as the base.

For example:

$\ln(7)$ln(7)

Natural logarithms are commonly used in calculus, finance, and scientific calculations.
