6.10/6.11 Laws of Logarithms and change of base formula

Laws of Logarithms (you don’t need to write exp. Laws) Exponent LawsLogarithm Laws

Express as a single logarithm Ex)TOO)

Example

Ex ) Use log = 1

TOO) Use log = 1

Facts on Logs NEW !!!

Change-of-Base Formula base down low use your calculator base 10 Ex) log button on your calculator is base 10!!

Change-of-Base Formula **Remember no CASIOS on this test! base down low Write in log form Go around the world Starting with base Ex)

TOO: Use Change-of-Base Formula to solve: base down low Write as a single log
