**Condense the logarithmic expression below.**

\[ \log_7 2 + 2 \log_7 6 - \log_7 9 \]

To condense the logarithmic expression given, we can use the properties of logarithms:

1. **Product Property of Logarithms:**
\[ \log_b M + \log_b N = \log_b (MN) \]

2. **Power Property of Logarithms:**
\[ a \log_b M = \log_b (M^a) \]

3. **Quotient Property of Logarithms:**
\[ \log_b M - \log_b N = \log_b \left( \frac{M}{N} \right) \]

**Step-by-Step Solution:**

1. Apply the Power Property to the second term:
\[ 2 \log_7 6 = \log_7 (6^2) = \log_7 36 \]

2. Replace the second term in the original expression:
\[ \log_7 2 + \log_7 36 - \log_7 9 \]

3. Combine the first two terms using the Product Property:
\[ \log_7 (2 \cdot 36) - \log_7 9 = \log_7 72 - \log_7 9 \]

4. Finally, apply the Quotient Property to condense the expression:
\[ \log_7 \left( \frac{72}{9} \right) = \log_7 8 \]

So, the condensed form of the original logarithmic expression is:
\[ \log_7 8 \]

This transformation utilizes logarithmic properties to condense multiple logarithmic terms into a single logarithmic expression.
