`|z_1|=|z_2|` and `arg((z_1)/(z_2))=pi`, then `z_1+z_2` is equal to

|z_(1)|=|z_(2)| and arg((z_(1))/(z_(2)))=pi, then z_(1)+z_(2) is equal to

If |z_(1)|=|z_(2)| and arg (z_(1)//z_(2))=pi, then z 1 ​ +z 2 ​ is equal to

If |z_1|=|z_2| and arg(z_1)+arg(z_2)=pi/2 then (A) z_1z_2 is purely real (B) z_1z_2 is purely imaginary (C) (z_1+z_2)^2 is purely imaginary (D) arg(z_1^(-1))+arg(z_2^(-1))=-pi/2

If |z_(1)|=|z_(2)| and arg (z_(1)//z_(2))=pi, then find z_(1)+z_(2) .

If |z_(1)|=|z_(2)| and arg (z_(1)//z_(2))=pi, then find the of z_(1)z_(2).

If |z_(1)|=|z_(2)| and arg (z_(1)//z_(2))=pi, then find the of z_(1)z_(2).

If z_1 and z_2 both satisfy the relation z+overlinez=2|z-1| and arg(z_1-z_2)=pi/4, then Im(z_1+z_2) equals

If for complex numbers z_(1) and z_(2),arg(z_(1))-arg(z_(2))=0 then |z_(1)-z_(2)| is equal to
