Thanks for doing this vids Dr. Fraser...you've helped me out a ton!

Properties of Logarithms

  • Use the properties either to convert the log of a complex expression into a combination of logs of simple expressions, or vice versa.

  • To solve a logarithmic equation, first use the properties to combine logs on each side of the equation to get an equation of the form log x = log y. Then equate x and y.
