To evaluate ln(1), find the exponent you must raise e (Euler's number, ≈ 2.71828) to in order to get 1.
Step 1 — Recall the definition
The natural logarithm ln(x) is the logarithm with base e:
ln(1) = n means en = 1
Step 2 — Apply the zero exponent property
Any positive number raised to the power 0 equals 1:
e0 = 1
Since e^0 = 1, we have ln(1) = 0.
ln(1) = 0
