What is ln 1,380?

Answer

ln 1,380 ≈
7.2298

ln is the natural log, base e ≈ 2.71828.

≈ — the logarithm is irrational; the value is rounded to 4 decimal places.

ln 1,380 is the power you raise e ≈ 2.71828 to, to get 1,380: ey = 1,380.

e⁷ ≈ 1,096.6332 < 1,380 < e⁸ ≈ 2,980.9580, so 7 < ln 1,380 < 8
