What is log₂ 27?
Answer
log2 27 ≈
4.7549
log2 is the log base 2.
≈ — the logarithm is irrational; the value is rounded to 4 decimal places.
log2 27 is the power you raise 2 to, to get 27: 2y = 27.
2⁴ = 16 < 27 < 32 = 2⁵, so 4 < log2 27 < 5
log2 27 = ln 27 / ln 2 ≈ 3.295837 / 0.693147 ≈ 4.7549
Answer point ≈ (27, 4.7549).
The curve y = log2 x passes through (1, 0) and (2, 1) and rises: for x > 1 the log is positive, for 0 < x < 1 negative.
