diketahui log3=0,477 dan log5= 0,699 tentukan nilai log 135

log 3 = 0,477
log 5 = 0,699

log 135 = log (3x3x3x5)
log 135 = log 3 + log 3 + log 3 + log 5
log 135 = 3 ( log 3 ) + log 5
log 135 = 3 ( 0,477 ) + ( 0,699 )
log 135 = 1,431 + 0,699
log 135 = 2,13

log3=0,477
log5= 0,699

log135
= log(27 . 5)
= log27 + log5
= log3³ + log5
= 3 . log3 + log5
= 3(0,477) + (0,699)
= 1,431 + 0,699
= 2,13
