We have the equation:

\[
e^{8x} = 8e^x
\]

To solve for \( x \), follow these steps:

### Step 1: Divide both sides of the equation by \( e^x \) (assuming \( e^x \neq 0 \)):

\[
\frac{e^{8x}}{e^x} = \frac{8e^x}{e^x}
\]

This simplifies to:

\[
e^{7x} = 8
\]

### Step 2: Take the natural logarithm (ln) of both sides:

\[
\ln(e^{7x}) = \ln(8)
\]

Using the logarithmic property \( \ln(e^a) = a \), we get:

\[
7x = \ln(8)
\]

### Step 3: Solve for \( x \):

\[
x = \frac{\ln(8)}{7}
\]

This is the exact solution. Numerically, using the approximation \( \ln(8) \approx 2.079 \), we get:

\[
x \approx \frac{2.079}{7} \approx 0.297
\]

Thus, \( x \approx 0.297 \).
