X + log b Y Product Rule for Logarithms The following examples show how to expand logarithmic expressions using each of the rules above. Example 1 Expand log 2 49 3 log 2 49 3 = 3 • log 2 49 Use the Power Rule for Logarithms. The answer is 3 • log 2 49 Example 2 Expand log 3 (7a) log 3 (7a) = log 3(7 • a) Since 7a is the product of 7 and ...

log(x) 5 [*] More in-depth mathematics log(x) is defined for x> 0. exp(x) is defined ∀x∈ R. If log(·) and exp(·) are defined as inverses of each other, isn’t that circular rea-soning? Yes. There is an alternative definition of the logarithm that provides a way out of the “chicken and egg” problem: log(x) = Z x 1 1 t dt and note ...

Logarithms allow solving many equations where the unknown variable x appears as an exponent. The logarithm function has several very useful relationships or “rules”. (The first four relationships are true for any fixed base b, so we can omit the b when listing them.) 1. log(a c) log(a) log(c) [log of a product] 2. log log(a) log(c) c a
