What is log 5?
Answer
log 5 ≈
0.6990
log here is the common log, base 10.
≈ — the logarithm is irrational; the value is rounded to 4 decimal places.
log 5 is the power you raise 10 to, to get 5: 10y = 5.
10⁰ = 1 < 5 < 10 = 10¹, so 0 < log 5 < 1
log 5 = ln 5 / ln 10 ≈ 1.609438 / 2.302585 ≈ 0.6990
Answer point ≈ (5, 0.6990).
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.
