Final answer:
The expression log3(C/9) is equivalent to option C)): log3C - log3(9).
Step-by-step explanation:
The expression log₃(C/9) can be simplified using the logarithmic property :
log(a/b) = log(a) - log(b).
Using this property, the equivalent expression can be rewritten as :
log₃C - log₃(9).
Therefore, the correct answer is option C: log₃C - log₃(9).
