log, short for logarithm, is a function in math that is often used in many different scenarios. It appears as an equation, such as log(x).

There are two parts of the log equation. First, the number within the parenthesis, then there is the exponent which is often called the base. The base is set to 10 by default as that is the way the default function works, but with our tool, you can change the value of the base.

Practical Applications of Logarithms

Logarithms have practical uses in various fields such as engineering, finance, and science. Some examples include:

Determining exponential growth or decay (e.g., population, radioactive decay).

Scaling in measurements, like the Richter scale for earthquakes or decibels for sound intensity.

Simplifying calculations in scientific and mathematical research.

Logarithm - Frequently Asked Questions

When you see a log equation without the base specifically defined, the base is equal to 10. This is commonly referred to as the common log.

A log equation will always have a base value, but if it is not explicitly written out, it has a base of 10 by default.

log 0 is undefined and does not exist.
