Diketahui 2 log 3 = p dan 3 log 5 = 9, tentukan dalam p dan q. A. 15 Log 6 = B. 6 log 5 =

A. 15 log 6 = 3 log 6 / 3 log 15
= 3 log (3 . 2) / 3 log (3 . 5)
= (3 log 3 + 3 log 2) / (3 log 3 + 3 log 5)
= (1 + 1/p) / (1 + q)
= (p + 1) / p (q + 1)

B. 6 log 5 = 3 log 5 / 3 log 6
= q / 3 log (3 .2)
= q / (3 log 3 + 3 log 2)
= q / (1 + 1/p)
= pq / (p + 1)
