Soal try out matematika tentang logaritma ? tolong di bantu ya guys

Answer 1

Mapel : Matematika
Kelas : X SMA
Bab : Logaritma

Pembahasan :
³log 12 - ³log (1/2) - ³log 8 + ³log 9
= ³log (12/2) - ³log 8 + 2
= ³log 6 - ³log 8 + 2
= ³log (6/8) + 2
= -0,2 + 2
= -2,2

Answer 2

³log 12 - ³log 1/2 - 3 . ³log 2 + ³log 9
= ³log 12 - ³log 1/2 - ³log 2³ + ³log 9
= ³log (12 ÷ 1/2 ÷ 8 x 9)
= ³log (24 ÷ 8 x 9)
= ³log 27
= ³log 3³
= 3 . ³log 3
= 3
