If Z1= a+bi and Z2 =
c+di then their addition is given by……….
a)(a+c)+(b+d)i
b)(ac-bd)+(ad+bc)i
c) (a-c)+(b-d)i
d) [(ac+bd)/c2+d2] + [(bc-ad)/(c2+d2)]i
If Z1= a+bi and Z2 = c+di then their
subtraction is given by
a)(a+c)+(b+d)i
b)(ac-bd)+(ad+bc)i
c)(a-c)+(b-d)i
d) [(ac+bd)/c2+d2] + [(bc-ad)/(c2+d2)]i
