Logarithm help needed

Answer 1

Answer:

The answer to your question is: log₇ ($\frac{xy}{z}$)

Step-by-step explanation:

                          log₇ x + log₇ y - log₇ z

First he must use the product rule that says:

                         log a x + log a y = log a xy

Then, he must use the quotient rule that says

                         log a x - log a y = log a ($\frac{x}{y}$

He did not use these rules that's why his answer is incorrect.

The correct answer is:

                        log₇ (xy) - log₇ z

                       log₇ $\frac{xy}{z}$
