If `z_(1)` and `z_(2)` are two non-zero complex number such that `|z_(1)z_(2)|=2` and `arg(z_(1))-arg(z_(2))=(pi)/(2)` ,then the value of `3iz_(1)z_(2)`

If z_(1) and z_(2), are two non-zero complex numbers such tha |z_(1)+z_(2)|=|z_(1)|+|z_(2)| then arg(z_(1))-arg(z_(2)) is equal to

If z_(1)andz_(2) are two complex numbers such that |z_(1)|=|z_(2)| and arg(z_(1))+arg(z_(2))=pi, then show that z_(1),=-(z)_(2)

If z_(1)-z_(2) are two complex numbers such that |(z_(1))/(z_(2))|=1 and arg (z_(1)z_(2))=0, then

arg((z_(1))/(z_(2)))=arg(z_(1))-arg(z_(2))

If z and w are two non - zero complex numbers such that |zw|=1 and arg(z)-arg(w)=(pi)/(2), then the value of 5ibarzw is equal to

If z_(1), and z_(2) are the two complex numbers such that|z_(1)|=|z_(2)|+|z_(1)-z_(2)| then find arg(z_(1))-arg(z_(2))

If z_(1) and z_(2) are to complex numbers such that two |z_(1)|=|z_(2)|+|z_(1)-z_(2)| , then arg (z_(1))-"arg"(z_(2))

If z_(1) and z_(2), are two non-zero complex numbers such that |z_(1)+z_(2)|=|z_(1)|+|z_(2)| then arg(z_(1))-arg(z_(2)) is equal to (1)0(2)-(pi)/(2) (3) (pi)/(2)(4)-pi
