Answer 2

Let's calculate the expression step by step:

1. Add the numbers inside the parentheses: (23,32 + 54,58) = 23,32 + 54,58 = 77,90 (1,202 + 0,698) = 1,202 + 0,698 = 1,900

2. Perform the multiplication: (77,90)*(1,900) = 147,210

3. Subtract the numbers inside the second parentheses: (3,53 - 1,89) = 3,53 - 1,89 = 1,64

4. Multiply by 2.1: 2,1*(1,64) = 3,384

Now, let's combine the results:

(23,32 + 54,58)(1,202 + 0,698) - 2,1(3,53 - 1,89) = 147,210 - 3,384 ≈ 143,826

So, the final result of the expression is approximately 143.826.
