Answer 3

It seems like you're working with complex numbers, where each number is represented in the form (a, b), where 'a' is the real part and 'b' is the imaginary part. To perform the given calculations, let's break down the expression step by step:

(2, 6 + (-4, 2)) + (4, 2 * (-2, 5))

Step 1: Perform addition and multiplication within parentheses: (2, 6 - 4, 2) + (4, -5)

Step 2: Combine the real and imaginary parts separately for each pair of complex numbers: (2 - 4) + (6 + 2) + (4 - 5)

Step 3: Simplify the expressions: -2 + 8 - 1

Step 4: Add the remaining real numbers: 5 - 1

Step 5: Final result: 4

Therefore, the result of the expression (2, 6 + (-4, 2)) + (4, 2 * (-2, 5)) is 4.
