The problem asks you to evaluate the exponential expression:

$6 \cdot (4 + 2)^2 - 3^2$

Let's solve this step by step:

Step 1: Simplify the parentheses

$4 + 2 = 6$

So the expression becomes: $6 \cdot 6^2 - 3^2$

Step 2: Calculate the exponents

$6^2 = 36 \quad \text{and} \quad 3^2 = 9$

Substitute these values into the expression: $6 \cdot 36 - 9$

Step 3: Perform multiplication

$6 \cdot 36 = 216$

Now the expression is: $216 - 9$

Step 4: Perform subtraction

$216 - 9 = 207$

Final Answer:

The value of the expression is: $\boxed{207}$
