Answer:
The answer is 1677.
To solve the expression, we must follow the order of operations:
1. First, we must calculate the power of 6:
6^2 = 36
2. Then, we must solve the expression inside the parentheses:
3 + 36 = 39
3. Next, we multiply 3 by 39:
3 × 39 = 117
4. We multiply 5 by 117:
5 × 117 = 585
5. Finally, we add 12 to 585:
585 + 12 = 597
Therefore,
5 * 3(3 + 6^2) + 12 = 597.
