Question

(−8,25 + (-7,13)) + (−1,49).

Answer 1

Ответ: (−8,25 + (-7,13)) + (−1,49)=-1,61

Answer 2

To solve this expression, we'll perform the addition operation step by step.

Let's start with the first set of parentheses: (−8,25 + (-7,13)).

To add complex numbers, we add their real parts and imaginary parts separately.

Real part: -8 + (-7) = -15.

Imaginary part: 25 + 13 = 38.

So, (−8,25 + (-7,13)) simplifies to (-15, 38).

Now let's add this result to the second complex number, (−1,49).

Real part: -15 + (-1) = -16.

Imaginary part: 38 + 49 = 87.

Therefore, the final result is (-16, 87).
