If Z_(1),Z_(2),Z_(3) are complex numbers such that |Z_(1)|=|Z_(2)|=|Z_(3)|=|(1)/(Z_(1))+(1)/(Z_(2))+(1)/(Z_(3))|=1 Then find the value of |Z_(1)+Z_(2)+Z_(3)| is :

if z_(1)=3+i and z_(2) = 2-i, " then" |(z_(1) +z_(2)-1)/(z_(1) -z_(2)+i)| is

if z_(1)=3+i and z_(2) = 2-i, " then" |(z_(1) +z_(2)-1)/(z_(1) -z_(2)+i)| is

If |z_(1)|=1,|z_(2)|=2,|z_(3)|=3 ,then |z_(1)+z_(2)+z_(3)|^(2)+|-z_(1)+z_(2)+z_(3)|^(2)+|z_(1)-z_(2)+z_(3)|^(2)+|z_(1)+z_(2)-z_(3)|^(2) is equal to
