practice expanding logarithmic expressions.[br][br]For video explanation see[br][url=https://www.khanacademy.org/math/algebra/logarithms-tutorial/logarithm_properties/v/using-multiple-logarithm-properties-to-simplify]https://www.khanacademy.org/math/algebra/logarithms-tutorial/logarithm_properties/v/using-multiple-logarithm-properties-to-simplify[/url][br]or [url=http://patrickjmt.com/properties-of-logarithms/]http://patrickjmt.com/properties-of-logarithms/[/url] (this video does more than just expanding logarithms)[br][br]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.
