    What is ln 5?

    Answer

    ln 5 ≈
    1.6094

    ln is the natural log, base e ≈ 2.71828.

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

    ln 5 is the power you raise e ≈ 2.71828 to, to get 5: ey = 5.

    e¹ ≈ 2.7183 < 5 < e² ≈ 7.3891, so 1 < ln 5 < 2

    Oxy1

    Answer point ≈ (5, 1.6094).

    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.
