Evaluate logarithms — log, ln, and any base — step by step.
Expression
Answer
4.605170
To evaluate ln(100), find the exponent you must raise e (Euler's number, ≈ 2.71828) to in order to get 100.
Step 1 — Recall the definition
The natural logarithm ln(x) is the logarithm with base e:
ln(100) = n means en = 100
Step 2 — Evaluate
ln(100) does not simplify to a nice closed form. Use the definition or a calculator:
ln(100) ≈ 4.605170
This means e^4.605170 ≈ 100.
ln(100) ≈ 4.605170
