Question

simplify the expression.
\ln e^{15} = \square

Explanation:

Step1: Recall the logarithm property

The natural logarithm $\ln$ and the exponential function $e^x$ are inverse functions. The property is $\ln(e^x) = x$ for any real number $x$.

Step2: Apply the property

In the given expression $\ln(e^{15})$, we can apply the property $\ln(e^x)=x$ with $x = 15$. So $\ln(e^{15})=15$.

Answer:

15
