Answer

So, the simplified form of the given natural logarithm is \(\boxed{-\frac{1}{a}}\).

Steps

Step 1 :Given the natural logarithm \(\ln \left(e^{-1 / a}\right)\).

Step 2 :The natural logarithm and the exponential function are inverse functions. Therefore, the natural logarithm of an exponential function simplifies to the exponent of the exponential function.

Step 3 :In this case, the exponent is \(-1/a\).

Step 4 :So, the simplified form of the given natural logarithm is \(\boxed{-\frac{1}{a}}\).
