tolooongg bantuin yaa sama caranyaaa...mau dikumpulin ni mkassiiii

log 2 = p
log 3 = q

log 120
= log 10.4.3
= log 10 + log 4 + log 3
= log 10 + log 2^2 + log 3
= log 10 + 2 . log 2 + log 3
= 1 + 2 . p + q
= 1 + 2p + q ......(C)


Moga membantu....

[tex] log \: 120 \\ = log \: 12 + log \: 10 \\ = log \: 6 + log \: 2 + log \: 10 \\ = log \: 3 + log \: 2 + log \: 2 + log \: 10 \\ = q + p + p + 1 \\ = q + 2p + 1[/tex]

Jadi, jawabannya C. (1 + 2p + q).
