Solution Steps
To solve the exponential equation \(3^x = 6\), we can take the natural logarithm of both sides to linearize the equation. This allows us to solve for \(x\) using properties of logarithms.
Step 1: Take the Natural Logarithm of Both Sides
To solve the equation \(3^x = 6\), we take the natural logarithm of both sides:
\[
\ln(3^x) = \ln(6)
\]
Step 2: Use Logarithm Properties
Using the property of logarithms \(\ln(a^b) = b \ln(a)\), we can rewrite the equation as:
\[
x \ln(3) = \ln(6)
\]
Step 3: Solve for \(x\)
Isolate \(x\) by dividing both sides by \(\ln(3)\):
\[
x = \frac{\ln(6)}{\ln(3)}
\]
Step 4: Calculate the Exact Value
Using the natural logarithm values:
\[
x \approx \frac{1.7918}{1.0986} \approx 1.6309
\]
Final Answer
The solution set is:
\[
\boxed{x = \frac{\ln(6)}{\ln(3)}}
\]
The answer is A.
