Question

Use the product property of logarithms to write the logarithm as a sum of logarithms. Then simplify if possible.log9 (xy)

Answer 1

Recall the Product Property of Logarithms below:

$log_b(x\cdot y)=\log_bx+\log_by$

It tells us that the log of the product of the two terms is the sum of the log of each term.

Hence, log₉ (xy) = log₉ x + log₉ y. (Option D)
