Question

Jika 2log 3 =a dan 2log 5 = b
maka 2log 60=…

Answer 1

2log60 =
2log60 / 2log2
2log3 + 2log5 + 2log2 + 2log2 / per 2log2
= a + b + 1 + 1 per 1
= 2 + a + b per 1

Answer 2

2 log 3 = a , 2log5 = b
2log60 = 2log5.2.2.3
             = 2log 5 +2log2+ 2log2 + 2log3
             = b + 1+ 1+ a
             = a+b+2
