diket: log 2 = 0,3010 ..... log 3= 0,4771....... log 5= 0,6989 pertannyaan. log 60= log135= tolong bantu ina ya . ina ngk ngerti

Log 60 = 1,778 , Log 135 = 2,1302

log 60 = log (4.3.5)
= log (2^2.3.5)
= log 2^2 + log 3 + log 5
= 2.log 2 + log 3 + log 5
= 2. 0,3010 + 0,4771 + 0,6889
= 1,7890
log 135 = log ( 27.5)
= log (3^3.5)
= log 3^3 + log 5
= 3.log 3 + log 5
= 3.0,4771 + 0,6889
= 2,1202. semoga membantu...!
