Jika ³ log 2 = a dan ³ log 5 = b, maka nilai ³ log 100 adalah...
![]()
Penjelasan dengan langkah-langkah:
³log 2 = a
³log 5 = b
³log 100
= ³log (2² × 5²)
= ³log 2² + ³log 5²
= 2 × ³log 2 + 2 × ³log 5
= 2 × a + 2 × b
= 2a + 2b
atau
³log 100
= ³log (2 × 5)²
= 2 × (³log (2 × 5))
= 2 × (³log 2 + ³log 5)
= 2 × (a + b)
= 2(a + b)
= 2a + 2b
