Properties of Logarithms

  1. \rhd  Intro to logarithm properties (1 of 2) (9:15) Examples illustrating the properties \log_BA+\log_BC=\log_B(AC) and \log_BA-\log_BC=\log_B\left(\dfrac{A}{C}\right).
  2. \rhd  Intro to logarithm properties (2 of 2) (10:04) Examples illustrating the properties A\cdot\log_BC=\log_B\left(C^A\right) and \log_BA=\dfrac{\log_CA}{\log_CB} (change of base formula).  This video also shows how to find \log_2 \left(\sqrt{\dfrac{32}{\sqrt 8}}\right).
  3. * Practice Type of problem: (scroll down)
    • Find \log_2(3a).
    • Condense \log_5(2y)+\log_5(8).
    • Expand \log_b\left(\dfrac{4}{c}\right).
    • Condense \log(3z)-\log(8).
    • Expand \log_7(x^5).
    • Condense 6\ln y.
    • + challenge problems
  4. \rhd Using the properties of logarithms: multiple steps (2:09) Simplify \log_5\dfrac{25^x}{y}.
