A useful property of logarithms states that the logarithm of a product of two quantities is the sum of the logarithms of the two factors. In symbols, logo(XY)=logo(x)+logo(y). (x y) = log b (x) + log b

The rule is that you keep the base and add the exponents. Well, remember that logarithms are exponents, and when you multiply, you're going to add the logarithms. The log of a product is the sum of the logs.
The identities of logarithms can be used to approximate large numbers. Note that logo(a) + logo(c) = logo(ac), where a, b, and c are arbitrary constants.
Division. The rule when you divide two values with the same base is to subtract the exponents. Therefore, the rule for division is to subtract the logarithms. The log of a quotient is the difference of the logs.
The logarithm of an exponential number is the exponent times the logarithm of the base. The logarithm of a number that is equal to its base is just 1. Rule 6: Log of Exponent Rule. The logarithm of an exponential number where its base is the same as the base of the log equals the exponent.
