Question

Hasil dari:
1. ³log 9 + ³log 6 - ³log 3 - ³log 2
2. ³log 6 + ³log 18 + ³log 9 - ³log 27 - ³log 12

Answer 1

1. ³log 9 + ³log 6 - ³log 3 - ³log 2
= ³log 9 X 6 - ³log 3 - ³log 2
= ³log 54 - ³log 2
          3
= ³log 18
       2
= ³log 9
= 2

2. ³log 6 + ³log 18 + ³log 9 - ³log 27 - ³log 12
= ³ log 6 X 18 X 9 - ³log 27 - ³log 12
= ³log 972 - ³log 12
         27
³ log 36
       12
= ³ log 3
= 1
