What is log₂ 7?
Answer
log2 7 ≈
2.8074
log2 is the log base 2.
≈ — the logarithm is irrational; the value is rounded to 4 decimal places.
log2 7 is the power you raise 2 to, to get 7: 2y = 7.
2² = 4 < 7 < 8 = 2³, so 2 < log2 7 < 3
log2 7 = ln 7 / ln 2 ≈ 1.945910 / 0.693147 ≈ 2.8074
Answer point ≈ (7, 2.8074).
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.
