    What is ln 100?

    Answer

    ln 100 ≈
    4.6052

    ln is the natural log, base e ≈ 2.71828.

    ≈ — the logarithm is irrational; the value is rounded to 4 decimal places.

    ln 100 is the power you raise e ≈ 2.71828 to, to get 100: ey = 100.

    e⁴ ≈ 54.5982 < 100 < e⁵ ≈ 148.4132, so 4 < ln 100 < 5

    Answer point ≈ (100, 4.6052).

    The curve y = ln x passes through (1, 0) and (e, 1) and rises: for x > 1 the log is positive, for 0 < x < 1 negative.
