_______
Log 6
=log7+log7+log2
______________
Log3 +log 2
=2log7+2log7+2log2
_________________
2log2+2log3
=1/a+1/a+1
--------------
1+b
jadi
7 log2 : a
2 log 3 : b
maka untuk penyelesaian 6 log 98 adalah
2 log 98 / 2 log 6
8
inget sifat sifat yah disini, jadi :
=(2 log 2 + 2 log 7 + 2 log 7) / (2 log 2 + 2 log 3)
=(1 + (1/a) + (1/a) ) / ( 1+b)
= ( a+2 / a ) . b
= ab + 2b / a
aga bingung, kalo salah mohon koreksi nya :D
