The given expression is:

\[
\ ^2 \log 8 + ^2 \log 6 - ^2 \log 3
\]

This notation suggests that we are dealing with logarithms of base 2. Thus, it can be written as:

\[
\log_2 8 + \log_2 6 - \log_2 3
\]

### Step-by-step solution:

1. **Simplify each term**:
   - \( \log_2 8 \): Since \( 8 = 2^3 \), we have \( \log_2 8 = 3 \).
   - \( \log_2 6 \): We can leave \( \log_2 6 \) as is because it cannot be simplified further using powers of 2.
   - \( \log_2 3 \): Similarly, \( \log_2 3 \) stays as is.

2. **Apply logarithmic properties**:
   Using the property \( \log_b (A) + \log_b (B) = \log_b (A \cdot B) \), we combine the first two terms:

   \[
   \log_2 (8 \cdot 6) = \log_2 48
   \]

   Now the expression becomes:

   \[
   \log_2 48 - \log_2 3
   \]

3. **Simplify further**:
   Using another property \( \log_b (A) - \log_b (B) = \log_b \left( \frac{A}{B} \right) \), we can combine the remaining terms:

   \[
   \log_2 \left( \frac{48}{3} \right) = \log_2 16
   \]

4. **Final result**:
   Since \( 16 = 2^4 \), we have:

   \[
   \log_2 16 = 4
   \]

Thus, the value of the expression is **4**.
