log2+log20-log5+log50-log4=

1 Jawaban

  • log2 + log20 - log5 + log50 - log4 =
    log2 + log20 + log50 - log5 - log4 =
    log2 + log20 + log50 - (log5 + log4) =
    log(2 x 20 x 50) - (log(5 x 4)) =
    log 2.000 - log 20 =
    log(2.000 / 20) =
    log 100 =
    log 10² =
    2 x log10 =
    2 x 1 =
    2

    maka,
    log2 + log20 - log5 + log50 - log4 = 2
