(5-4i)+(7+2i) (-2+3i)-(7-2i) (-6+2i)+(-6-2i) (1-i)-(7-3i)+(6-2i)-(2+i) (-2+3i)*(7-2i)...

Question

(5-4i)+(7+2i)
(-2+3i)-(7-2i)
(-6+2i)+(-6-2i)
(1-i)-(7-3i)+(6-2i)-(2+i)
(-2+3i)*(7-2i)
(5-4i)*(3+2i)
1/1-i

Answer 1

(5-4i)+(7+2i)=5-4і+7+2і=12-2і
(-2+3i)-(7-2i)=-2+3і-7+2і=5і-9
(-6+2i)+(-6-2i)=-6+2і-6-2і=-12
