logb(a) is undefined if a is negative. logb(0) is undefined for any base b. logb(bn) = n, for any base b. The Common and Natural Logarithms . A logarithm can have any positive value as its base, but two log bases are more useful than the others. The base-10, or "common", log is popular for historical reasons, and is usually written as "log(x)".

The logarithm laws are obtained from the index laws and are: Note: It is not possible to have the logarithm of a negative number. All logarithms must have the same base. Simplifying logarithms The logarithm laws can be used to simplify logarithmic expressions. Example 1 . Express the following as a single logarithm. (Remember the logarithms ...

For example, the number 4000 has one significant digit; the zeros don’t count because there’s no nonzero digit after them. But the number 4000.5 has five significant digits: the 4, the 5, and all the zeros in between. And the number 0.003 has three significant digits: the 3 and the two zeros that come between the 3 and the decimal point ...
