    What is ln 30?

    Answer

    ln 30 ≈
    3.4012

    ln is the natural log, base e ≈ 2.71828.

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

    ln 30 is the power you raise e ≈ 2.71828 to, to get 30: ey = 30.

    e³ ≈ 20.0855 < 30 < e⁴ ≈ 54.5982, so 3 < ln 30 < 4

    Answer point ≈ (30, 3.4012).

    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.
