2 Jawaban

  • 3 log 16 = 3 log 2⁴
                   = 4 ³ log 2
    2 log 27 = 2 log 3³
                   = 3 ²log 3
    4 ³ log 2 × 3 ²log 3
    12 ³ log 2 ²log 3
    12  ³log3
    12. 1
    = 12
  • 3'log 16 × 2'log 27
    = 3'log 2^4 × 2'log 3^3
    = 4 × 3'log 2 × 3 × 2'log 3
    = 4 × 3 × 3'log 2 × 2'log 3
    = 12 × 3'log 3
    = 12 × 1
