What is log 9?
Answer
log 9 ≈
0.9542
log here is the common log, base 10.
≈ — the logarithm is irrational; the value is rounded to 4 decimal places.
log 9 is the power you raise 10 to, to get 9: 10y = 9.
10⁰ = 1 < 9 < 10 = 10¹, so 0 < log 9 < 1
log 9 = ln 9 / ln 10 ≈ 2.197225 / 2.302585 ≈ 0.9542
Answer point ≈ (9, 0.9542).
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.
