Question

Jika log 2 = a , log 3=b , dan log 5 = c , nilai log 60 =

Answer 1

Log 60
=log(5.30)
=log5 + log(3.10)
=log 5 + log 3 + log 10
=log 5 + log 3 + log(2.5)
=log 5 + log 3 + log 2 + log 5
=c + b + a + c
=2c + a. + b

Answer 2

Pembahasan.

DIKETAHUI

Log 2 = a
Log 3 = b
Log 5 = c

Log 60 bisa kita pecah menjadi

Log ( 3 . 2 . 5 . 2 )
Log ( 3 . 4 . 5 )
Log 3 + Log 4 + Log 5
b + 2.Log 2 +c
b + 2a + c
2a + b + c
