Limit x mendekati 0 1-√x+1 dibagi x² -x

1 Jawaban

  • Lim 1 - √x + 1 / x² - x
    x→0

    Lim 1 - (x + 1) / (x² - x) (1 + √x + 1)
    x→0

    Lim 1 - x - 1 / (x² - x)(1 + √x + 1)
    x→0

    Lim -x / x(x - 1) (1 + √x + 1)
    x→0

    Lim -1 / (x - 1)(1 + √x + 1)
    x→0

    = -1 / (0 - 1)(1 + √0+1)

    = -1 / (-1)(1 + √1)

    = -1 / (-1)(1 + 1)

    = -1 / (-1)(2)

    = -1 / - 2

    = 1/2
