Question

think now: 02.10. 2026
possible points: 0.25
add: $(4 - 3i) + (1 - 6i) + (4 + 5i)$
$7 + 8i$
$5 - 9i$
$1 - 14i$
$9 - 4i$

Explanation:

Step1: Group real and imaginary parts

$(4+1+4) + (-3i-6i+5i)$

Step2: Calculate real part sum

$4+1+4 = 9$

Step3: Calculate imaginary part sum

$-3-6+5 = -4$, so $-4i$

Step4: Combine results

$9 + (-4i) = 9-4i$

Answer:

$9 - 4i$ (corresponding to the option: $9 - 4i$)
