Answer 3

Let's solve the expression step by step:

1. Calculate the values inside the parentheses first: (806 * 450 + 430 * 180) = 419700

2. Perform the next operation: 419700 * 1310 = 549627000

3. Subtract the value: 549627000 - 565020 = 549062980

4. Finally, divide by 657: 549062980 / 657 ≈ 834672.724

So, the result of the expression (806 * 450 + 430 * 180) * 1310 - 565020 / 657 is approximately 834672.724.
