Copy of Expanding Natural Logarithms-Section 6.2
practice expanding logarithmic expressions.
For video explanation see
https://www.khanacademy.org/math/algebra/logarithms-tutorial/logarithm_properties/v/using-multiple-logarithm-properties-to-simplify
or http://patrickjmt.com/properties-of-logarithms/ (this video does more than just expanding logarithms)
The answer it gives always puts the expression with x first, then y, then z. This is not necessarily the order you would put them in when you answer the questions.
