Solve the following logarithmic equation. Be sure to reject any value of $x$ that is not in the domain of the original logarithmic expression. Give the exact answer. Then, use a calculator to obtain a decimal approximation, correct to two decimal places, for the solution.
\[
\ln x=5
\]
Rewrite the given equation without logarithms. Do not solve for $\mathrm{x}$.
\[
e^{5}=\mathrm{x}
\]
Solve the equation. What is the exact solution? Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
A. The solution set is $\{\square$.
(Type an exact answer in terms of $e$.)
B. There are infinitely many solutions.
C. There is no solution.
Answer
Final Answer: The exact solution to the equation is \(e^5\). The decimal approximation of the solution, correct to two decimal places, is \(\boxed{148.41}\).
Step 1 ：Rewrite the given equation without logarithms: \(e^{5} = x\).
Step 2 ：Solve the equation to find the exact solution: \(x = e^{5}\).
Step 3 ：Use a calculator to obtain a decimal approximation, correct to two decimal places: \(x = 148.41\).
Step 4 ：Final Answer: The exact solution to the equation is \(e^5\). The decimal approximation of the solution, correct to two decimal places, is \(\boxed{148.41}\).
