Question:

Determine whether each equation is true or false. If false, rewrite one side of the equation to make it true. Check your answer on your calculator.
a. log 3 + log 7 = log 21
b. log 5 + log 3 = log 8
c. log 16 = 4 log 2
d. log 5 - log 2 = log 2.5
e. log 9 - log 3 = log 6
f. log (7 = log 7/2
g. log 35 = 5 log 7
h. log1/4 = - log4
i. log 3/ log 4 = log 3/4
j. log 64 = 1.5 log 16?
