# What is the common logarithm of 10?

Oct 15, 2014

A common logarithm means that the logarithm is of base 10.

To get the logarithm of a number $n$, find the number $x$ that when the base is raised to that power, the resulting value is $n$

For this problem, we have

${\log}_{10} 10 = x$

$\implies {10}^{x} = 10$

$\implies {10}^{x} = {10}^{1}$

$\implies x = 1$

Therefore, the common logarithm of 10 is 1.
