³log 12-3. ³log 2 + ³log 9. ³log½

semua log dicoret aja
jadi 9.2 + 9.1/2
18+4,5
=22,5

[tex] 3log_{12} - 3. 3log_{2} + 3log_{9}. 3log_{ \frac{1}{2} } \\ - 3.3 log_{ \frac{12}{2} } + 3 log_{ {3}^{2} }.3 log_{ \frac{1}{2} } \\ - 3.3 log_{6} + 2. 3log \frac{1}{2} \\ - 3 + 2. 3log_{6 \times \frac{1}{2} } \\ - 3 + 2. 3log_{3} \\ - 3 + 2.1 \\ - 1[/tex]
Maaf kalo salah, semoga membantu
