Question

Which expression is equivalent?

Answer 1

The correct option is: Option (C) $log_3c - log_{3}9$

Explanation:
It is the property of log that if it contains the fraction, it can be expressed as the difference of the log of numerator and the log of denominator.

The general form is:
$log( \frac{x}{y} ) = log(x) - log(y)$

Hence the correct answer is $log_3c - log_{3}9$.
