Just in case:
3log 2 = 1/a ; 5log3 = 1/b

1. 25log 36
= 3log36 / 3log25
= (3log 3 + 3log 3 + 3log 3 + 3log 4) / 3log 25
= (3+ 3log 4)/ 3log 25
= (3 + 2 x 3log2) / 2 3log 5
= (3+2/a)/2b

2. 2log 5 = 2log 3 x 3log 5 = axb
3. 30log 150
= 3log 150/ 3log 30
= (3log 3x5x5x2) / (3log 3x5x2)
= (3log 3 +3log 5 +3log 5 + 3log 2) /(3log 3 + 3log 5 + 3log 2)
= (1 + b + b + 1/a) / (1 + b + 1/a)
= (1+ 2b +1/a) / (1+b+1/a)
terimakasih atas jawabannya.
sama sama =)
