What is log 75?
Answer
log 75 ≈
1.8751
log here is the common log, base 10.
≈ — the logarithm is irrational; the value is rounded to 4 decimal places.
log 75 is the power you raise 10 to, to get 75: 10y = 75.
10¹ = 10 < 75 < 100 = 10², so 1 < log 75 < 2
log 75 = ln 75 / ln 10 ≈ 4.317488 / 2.302585 ≈ 1.8751
Answer point ≈ (75, 1.8751).
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.
| Base | Notation | Value |
|---|---|---|
| e | ln 75 | ≈ 4.3175 |
| 10 | log 75 | ≈ 1.8751 |
| 2 | log₂ 75 | ≈ 6.2288 |
