Let's expand the given logarithmic expression using properties of logarithms.

The expression is:

\[
\ln \left( \frac{x^3 \sqrt{x^2 + 2}}{(x + 2)^6} \right)
\]

### Step-by-step Expansion:

1. **Quotient Rule of Logarithms**:
   Using the property:
   \[
   \ln \left( \frac{A}{B} \right) = \ln(A) - \ln(B)
   \]
   We apply it to the expression:
   \[
   \ln \left( \frac{x^3 \sqrt{x^2 + 2}}{(x + 2)^6} \right) = \ln \left( x^3 \sqrt{x^2 + 2} \right) - \ln \left( (x + 2)^6 \right)
   \]

2. **Power Rule of Logarithms**:
   For the first term, we use the product rule:
   \[
   \ln(AB) = \ln(A) + \ln(B)
   \]
   This gives:
   \[
   \ln \left( x^3 \sqrt{x^2 + 2} \right) = \ln(x^3) + \ln(\sqrt{x^2 + 2})
   \]
   
   Then, apply the power rule:
   \[
   \ln(x^n) = n \ln(x)
   \]
   \[
   \ln(x^3) = 3 \ln(x)
   \]
   And for the square root:
   \[
   \ln(\sqrt{x^2 + 2}) = \ln \left( (x^2 + 2)^{1/2} \right) = \frac{1}{2} \ln(x^2 + 2)
   \]

3. **Simplify**:
   Now let's rewrite the expression with these simplifications:
   \[
   \ln \left( \frac{x^3 \sqrt{x^2 + 2}}{(x + 2)^6} \right) = 3 \ln(x) + \frac{1}{2} \ln(x^2 + 2) - \ln \left( (x + 2)^6 \right)
   \]
   
   Applying the power rule to the last term:
   \[
   \ln \left( (x + 2)^6 \right) = 6 \ln(x + 2)
   \]

4. **Final Expression**:
   Putting everything together, the expanded form is:
   \[
   3 \ln(x) + \frac{1}{2} \ln(x^2 + 2) - 6 \ln(x + 2)
   \]
