Change of Base Formula - Problem 2
Your calculator is programmed to only do logs of base 10 or base e, but we can find logs with any base using the change of base formula. Most errors come in not using parentheses properly when typing the logs into your calculator: make sure you do log ( ) top divided by log ( ) of the bottom!
