Question

Jika 2 log 3=b maka 9 log 12 adalah..
tolong dibantu ya bserta caranya..makasih

Answer 1

2log12/2log9
2log4.3/ 2log3^2
2log2^2+2log3 / 2. 2log3
2(1)+b / 2(b)
2+b/2b

Answer 2

2 log 3 = b
3 log 2 = 1/b
9 log 12 = 3^2 log 2^2.3
= 3^2 log 2^2 + 3^2 log 3
= 2/2 3 log 2 + 1/2 3 log 3
= 1/b + 1/2
= 2/2b + b/2b
= 2+b/2b

kalau gak salah
