common logarithm

mathematics
Also known as: Briggsian logarithm

Quick Summary

A common logarithm is a logarithm with a base of 10. It is also known as a Briggsian logarithm. The concept of logarithms was developed in the 17th century to simplify complex calculations, particularly multiplication, by converting them into addition.

Mathematically, if (b^x = n), then (x) is the logarithm of (n) to the base (b), written as (x = \log_b n). For a common logarithm, the base (b) is 10. For example, since (10^2 = 100), the common logarithm of 100 is 2, written as (\log 100 = 2).

Common logarithms were historically vital for scientific computations but have largely been superseded by mechanical calculators and computers for large-scale tasks. However, the principles of logarithms remain fundamental in various areas of mathematics and science.12
