2log12-3 2log3+2log18

[tex]^2log12 - 3 ^2log3+^2log18 \\ = ^2log(12.18/3^3) \\ = ^2log(3.2.2.3.3.2/3.3.3) \\ = ^2log(2^3.3^3/3^3) \\ = ^2log(2^3) \\ = ^2log8 \\ = 3[/tex]

Jadi, jawaban dari persamaan logaritma diatas adalah 3

Materi : Logaritma

Pembahasan :
²log 12 - 3 . ²log 3 + ²log 18
= ²log 12 + ²log 18 - 3 . ²log 3
= ²log (12 x 18) - ²log 3³
= ²log 216 - ²log 27
= ²log (216 : 27)
= ²log 8
= ²log 2³
= 3
