If `|z_1|=1,|z_2|=2,|z_3|=3,a n d|9z_1z_2+4z_1z_3+z_2z_3|=12 ,` then find the value of `|z_1+z_2+z_3|dot`

If |z_1|=1, |z_2| = 2, |z_3|=3 and |9z_1 z_2 + 4z_1 z_3+ z_2 z_3|=12 , then the value of |z_1 + z_2+ z_3| is equal to

If |z_1|=1, |z_2|=2, |z_3|=3 and |9z_1z_2 + 4z_1z_3 + z_2z_3|=36 , then |z_1+z_2+z_3| is equal to :

If |z_(1)|=1,|z_(2)|=2,|z_(3)|=3 and |9z_(1)z_(2)+4z_(1)z_(2)+z_(2)z_(3)|=12, then |z_(1)+z_(2)+z_(3)| is equal to

If z_1 = 3i and z_2 = -1 -i , find the value of arg z_1/z_2 .

If |z_(1)|=2,|z_(2)|=3,|z_(3)|=4and|z_(1)+z_(3)+z_(3)|=2 ,then the value of |4z_(2)z_(3)+9z_(3)z_(1)+16z_(1)z_(2)|

If |z_1|=2, |z_2|=3, |z_3|=4 and |2z_1+3z_2 + 4z_3|=9 , then value of |8z_2z_3 + 27z_3z_1 + 64z_1z_2|^(1//3) is :

If z_(1),z_(2),z_(3) are complex numbers such that |z_(1)|=|z_(2)|=|z_(3)|=1|(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),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)|=2.|z_(2)|=3.|z_(3)|=4and|z_(1),+z_(2)+z_(3)|=2, then the value of |4z_(2)z_(3)+9z_(3)z_(1)+16z_(1)z_(2)|
