About Log Base 10
The logarithm base 10, often written as log10(x) or simply log(x), is the power to which 10 must be raised to produce the number x. In other words, if y = log10(x), then 10y = x.
Log base 10 is commonly used in various fields such as science and engineering, particularly when dealing with measurements that span many orders of magnitude, like the Richter scale for earthquakes or the pH scale in chemistry.
Formula
$$ \log_{10}(x) = y \iff 10^y = x $$
Example
To calculate log10(100), we ask: "To what power must we raise 10 to get 100?". Since 102 = 100, log10(100) = 2.
