evaluate. write your answer as a whole number, proper fraction, or improper fraction in simplest form. 9 ln…

Explanation:

Step1: Recall natural - log property

The natural logarithm $\ln e = 1$ since the exponential function $y = e^{x}$ and the natural - logarithm function $y=\ln x$ are inverse functions, and $e^{1}=e$.

Step2: Multiply by 9

We have $9\ln e$, substituting $\ln e = 1$ into it, we get $9\times1$. $9\times1 = 9$

Answer:

$9$
