Answer 1

Ответ:

Пошаговое объяснение:

(2 + 3i) + (5 - i)  = (2 + 5) + (3 - 1)i = 7 + 2i

(3 + 2i) + (5 - i) = (3 + 5) + (2 - 1)i = 8 + i

(3 - 2i) - (5 + 1i) = (3 - 5) + (-2 - 1)i = -2 - 3i

(3 + 2i) - (5 - 1i) = (3 - 5) + (2 + 1)i = -2 + 3i

Answer 2

$\displaystyle\\(3i+2)+(5-i)=3i+2+5-i=7+2i\\\\\\(3+2i)+(5-i)=3+2i+5-i=8+i\\\\\\(3-2i)-(5+i)=3-2i-5-i=-2-3i\\\\\\(2i+3)-(5-i)=2i+3-5+i=-2+3i$
