Jika log 2 = 0,3010 dan log 7 = 0,8450 , maka log 35 dan log 98 adalah

Kelas 10 Matematika
Bab Logaritma

1] log 35 = log (7 . 5)
log 35 = log 7 + log 5
log 35 = 0,8450 + log (10/2)
log 35 = 0,845 + log 10 - log 2
log 35 = 0,845 + 1 - 0,3010
log 35 = 1,544

2] log 98 = log (2 . 49)
log 98 = log 2 + log 49
log 98 = 0,3010 + log 7²
log 98 = 0,301 + 2 . log 7
log 98 = 0,301 + 2 . 0,8450
log 98 = 0,301 + 1,69
log 98 = 1,991
