Jawaban :
3log 54 + 5log 100 – 3log 6 – 5log 4
= 3log 54 – 3log 6 + 5log 100 – 5log 4
= 3log (54:6) + 5log (100:4)
= 3log 9 + 5log 25
= 3log 3^2 + 5log 5^2
= 2.3log 3 + 2.5log 5
= 2+2
= 4
= 3log 54 – 3log 6 + 5log 100 – 5log 4
= 3log (54:6) + 5log (100:4)
= 3log 9 + 5log 25
= 3log 3^2 + 5log 5^2
= 2.3log 3 + 2.5log 5
= 2+2
= 4
