A common logarithm is a logarithm with base 10. We write log 10 (x) simply as log(x). The common logarithm of a positive number x satisfies the following definition. For x > 0, y = log(x) is equivalent to 10 y = x We read log(x) as, “the logarithm with base 10 of x” or “log base 10 of x.” The logarithm y is the exponent to which 10 must ...

Logarithms to the base 10 are called common logarithms. Over their long history, two notations developed: log b (read as ‘log b’) and log 10 b. These both represent the logarithm of b to the base 10. Logarithms to the base e are used in research, and are called natural logarithms. Once again two notations developed over a long period of ...

This law tells us how to add two logarithms together. Adding log A and log B results in the logarithm of the product of A and B, that is log AB. For example, we can write. log10 5 + log10 4 = log10(5 × 4) = log10 20. The same base, in this case 10, is used throughout the calculation. You should verify this by evaluating both sides separately ...
