Law of logarithms examples
WebExamples: Since 10 3 = 1000, log 10 ( 1000) = 3. Since 2 − 3 = 1 / 8, log 2 ( 1 / 8) = − 3. 10 log 10 ( 17) = 17 and 2 log 2 ( .038) = .038 Since a 0 = 1, no matter what a is, log a ( 1) = 0 . In general log a ( x) will be positive for x > 1 and negative for x < 1 . The domain of a x is ( − ∞, ∞), so the range of log a ( x) is ( − ∞, ∞). Weblog a M = log b M × log a b.
