Find the value of \( \Large log_{3}72-log_{3}8 \)

A) 2
B) 9
C) 8
D) 24

Correct Answer:

A) 2

Description for Correct answer:
\( \Large log_{3}72-log_{3}8 = log_{3} \left(9 \times 8\right)-log_{3}8 \)

=\( \Large log_{3}9+log_{3}8-log_{3}8 \)

=\( \Large log_{3}9 \)

=\( \Large log_{3}3^{2}=2log_{3}3 \)

=2
