Logarithm Problem Worksheet - Basic Level

The worksheet below is designed for students who are just learning the fundamental properties of logarithms.

logmab = logma + logmb (logarithm product property)
logm
a
b
= logma - logmb (logarithm quotient property)
logmak = k·logma (logarithm power property)
logab =
logma
logmb
(logarithm change of base property)
logab =
1
logba
(logarithm base switch property)
logm1 = 0 
logmm = 1
