2 Jawaban

  • 5 log (81) . 9 log 25
    = 5 log 9 . 9 log 25
    = 5 log 25
    = 2

    1/20 log 20 = 1

    = 2 + 1
    = 3
  • 5logV81.9log25+1/(20log20)
    = 5log9.9log25+1/(20log20)
    = 5log25+1/1
    = 2 + 1
    = 3

    atau

    5logV81.9log25+(1/20)log20
    = 5log9.9log25+20^(-1)log20
    = 5log25+20^(-1)log20
    = 2 - 1
    = 1
