Answer 2

To calculate the expression:

4 * (7.4 + 19 * (-2.97 + 3.07) * 20)

Let's break it down step by step:

1. First, calculate the expression inside the innermost parentheses: (-2.97 + 3.07) = 0.1
2. Now, substitute this result back into the expression: 4 * (7.4 + 19 * 0.1 * 20)
3. Next, calculate 19 * 0.1 * 20 = 38
4. Now, substitute this result back into the expression: 4 * (7.4 + 38)
5. Calculate the expression inside the outer parentheses: 7.4 + 38 = 45.4
6. Finally, multiply by 4 to get the final result: 4 * 45.4 = 181.6

So, the final result is 181.6.
