If `arg(bar z_1)=arg(z_2)` then

arg(bar(z))=-arg(z)

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

If arg (bar(z)_(1))= "arg" (z_(2)), (z ne 0) then

If |z_(1)|=|z_(2)| and arg z_(1) + arg z_(2)=0 then

If z_(1),z_(2),z_(3) are three complex numbers and A=|{:("arg z"_(1),"arg z"_(2),"arg z"_(3)),("arg z"_(2),"arg z"_(3),"arg z"_(1)),("arg z"_(3),"arg z"_(1),"arg z"_(2)):}| then A is divisible by

If the Arg bar z_(1) and Arg z_(2) are (pi)/(5) and (pi)/(3) respectively,find (Arg z_(1)+Argz_(2))

If z_(1), z_(2), z_(3) are three complex numbers and A= |("arg"z_(1),"arg"z_(2),"arg"z_(3)),("arg"z_(2),"arg"z_(3),"arg"z_(1)),("arg"z_(3),"arg"z_(1),"arg"z_(2))| then A is divisible by

arg(bar(z))+arg(-z)={{:(pi",","if arg (z) "lt 0),(-pi",", "if arg (z) "gt 0):},"where" -pi lt arg(z) le pi . If arga(4z_(1))-arg(5z_(2))=pi, " then " abs(z_(1)/z_(2)) is equal to
