Answer 2

I can help you with this math problem. Here are the steps to solve it:

- First, we need to simplify the parentheses by dividing 588 by 49 and 728 by 56. We get:

197 × (588 : 49 + 728 : 56) × 40 = 197 × (12 + 13) × 40

- Next, we need to add 12 and 13 inside the parentheses. We get:

197 × (12 + 13) × 40 = 197 × 25 × 40

- Then, we need to multiply 197 by 25 and by 40. We can use the distributive property to make it easier. We get:

197 × 25 × 40 = (200 - 3) × 25 × 40 = 200 × 25 × 40 - 3 × 25 × 40 = 200000 - 3000 = 197000

- Therefore, the final answer is:

197 × (588 : 49 + 728 : 56) × 40 = 197000
