Dijawab ya bang kak tolong …..

Mohon koreksi…
senang bisa membantu 🙂

F(n)/g(n) = (2^(n + 2) . 6^(n – 4)) / 12^(n – 1)
= 2^(n + 2) . 6^(n – 4) / (2 . 6)^(n – 1)
= 2^(n + 2) . 6^(n – 4) / 2^(n – 1) . 6^(n – 1)
= 2^(n + 2 – (n – 1)) . 6^(n – 4 – (n – 1))
= 2^(n + 2 – n + 1) . 6^(n – 4 – n + 1)
= 2^3 . 6^-3
= 2^3 / 6^3
= (2/6)^3
= (1/3)^3
= 1/27
