jawab beserta caranya ya makasih

[3log 25 . 5log 81 + 4log 2] / [3log 36 - 3log 4]
= [3log 5^2 . 5log 3^4 + (2^2)log 2^1] / [3log 36/4]
= [2 . 3log 5 . 4 . 5log 3 + 1/2 . 2log 2] / [3log 9]
= [2 . 4 . 3log 5 . 5log 3 + 1/2 . 1] / [3log 3^2]
= [8 . 3log 3 + 1/2] / [2 . 3log 3]
= [8 + 1/2] / 2
= [17/2] / 2
= 17/4

= 4 1/4

= 4,25
