Write three different, but equivalent, expressions for each of the following logs. For example: log(73/2) can be written as
, , , etc. Homework Help ✎
Use the properties of logarithms and exponents to help you rewrite these.
Simplify different parts of the expression to create new, equivalent expressions.
Simplify the argument:
Simplify the argument further:
Use the Power Property of Logarithms in reverse here.
Since n · logm(a) = logm(an), −2 log(5) = log(5−2).
Find two different ways to rewrite 5−2
(there are more than two ways to do this).
Refer to parts (a) and (b).
