Jika log 2=0.301 log 3 =0.4771 log 5=0.6989 maka log 0.125 dan log 135 ? dengan cara tolong

Logaritma

log 0,125
= log (1/8)
= log 1 - log 8
= 0 - ( log 2³)
= 0 - (3 . log 2)
= 0 - (3 . 0,301)
= 0 - (0,903)
= -0,903

log 135
= log (3³ x 5)
= log 3³ + log 5
= 3 x log 3 + log 5
= 3 x 0,4771 + 0,6989
= 1,4313 + 0,6989
= 2,1302
