Question
The image contains a mathematical problem and multiple-choice options for solving an exponential equation.

**Equation:**
\[ e^{3x} = 8 \]

**Options:**

1. \[ \frac{\ln 8}{3} \]

2. \[ \frac{8}{3 \cdot e} \]

3. \[ \frac{\ln 3}{8} \]

4. \[ (3 \ln 8) \]

Each option is accompanied by a radio button for selection. These options represent potential solutions for \(x\) in the equation given.

Expert Solution
Step 1

Given 

e3x=8

Taking ln (i.e., loge ) on both sides we get

ln (e3x)=ln 8

3x=ln 8          [Applying rule: ln ex=x]

x=ln 83
