    What is log₅ 4?

    Answer

    log5 4 ≈
    0.8614

    log5 is the log base 5.

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

    log5 4 is the power you raise 5 to, to get 4: 5y = 4.

    5⁰ = 1 < 4 < 5 = 5¹, so 0 < log5 4 < 1

    log5 4 = ln 4 / ln 5 ≈ 1.386294 / 1.609438 ≈ 0.8614

    Answer point ≈ (4, 0.8614).

    The curve y = log5 x passes through (1, 0) and (5, 1) and rises: for x > 1 the log is positive, for 0 < x < 1 negative.
