    What is log 25?

    Answer

    log 25 ≈
    1.3979

    log here is the common log, base 10.

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

    log 25 is the power you raise 10 to, to get 25: 10y = 25.

    10¹ = 10 < 25 < 100 = 10², so 1 < log 25 < 2

    log 25 = ln 25 / ln 10 ≈ 3.218876 / 2.302585 ≈ 1.3979

    Answer point ≈ (25, 1.3979).

    The curve y = log x passes through (1, 0) and (10, 1) and rises: for x > 1 the log is positive, for 0 < x < 1 negative.
