2. Diketahui 3log 6 = p dan 3log 2 = q. Nilai 24log 288 adalah ...
a. (2p + 3q)/ (p + 2q)
b. (3p + 2q)/ (p + 2q)
c. (p + 2q) / (2p + 3q)
d. (p + 2q)/ (3p + 2q)
e. (q + 2p) / (2p + 3q)
Jawaban :
3log 6 = p
3log 2 = q
24log 288
= 3log 288 / 3log 24
= 3log (6 . 6 . 8) / 3log (6 . 4)
= (3log (6^2) + 3log 8) / (3log 6 + 3log 4)
= (2 . 3log 6 + 3 3log 2) / (3log 6 + 3log 2^2)
= (2 . 3log 6 + 3 3log 2) / (3log 6 + 2 . 3log 2)
= (2p + 3q) / (p + 2q)
Jawaban : A
