Lesson #9: Laws of Logarithms
There is a lot of information in this lesson. It is suggested you take 2 or 3 days to work through the listed learning targets.
Learning Target
RF5.1 - I can write a logarithmic expression as a single logarithm, using the laws of logarithms.
RF5.2 - I can expand and combine logarithmic expressions using the laws of logarithms..
RF5.3 - I can use the laws of logarithms to simplify and evaluate logarithmic expressions.
RF5.4 - I can use the change of base formula to find the approximate value of a logarithmic expression.
RF5.2 - I can expand and combine logarithmic expressions using the laws of logarithms..
RF5.3 - I can use the laws of logarithms to simplify and evaluate logarithmic expressions.
RF5.4 - I can use the change of base formula to find the approximate value of a logarithmic expression.
