evaluate or simplify the expression without using a calculator. in 1 in 1 =

Explanation:

Step1: Recall logarithm property

The natural - logarithm function (y = \ln x) is the inverse of the exponential function (y = e^{x}), i.e., if (y=\ln x), then (x = e^{y}). We want to find (y) such that (e^{y}=1).

Step2: Use the exponential property

We know that for any non - zero real number (a), (a^{0}=1). In the case of the exponential function (y = e^{x}), when (x = 0), (e^{0}=1). Since (\ln x) and (e^{x}) are inverse functions, if (e^{0}=1), then (\ln1 = 0).
