3.If Z1, Z2, Z3, Z4 are roots of the equation 24 + 2 + z2 + z + 1 = 0, then least value of [121 + Z2|] + 1(1) denotes G.I.F.).

If z_(1),z_(2),z_(3),z_(4) are the roots of the equation z^(4)+z^(3)+z^(2)+z+1=0, then the least value of [|z_(1)+z_(2)|]+1 is (where [.] is GIF.)

let z_1,z_2,z_3 and z_4 be the roots of the equation z^4 + z^3 +2=0 , then the value of prod_(r=1)^(4) (2z_r+1) is equal to :

let z_1,z_2,z_3 and z_4 be the roots of the equation z^4 + z^3 +2=0 , then the value of prod_(r=1)^(4) (2z_r+1) is equal to :

If z_(1),z_(2),z_(3) andz_(4) are the roots of the equation z^(4)=1, the value of sum_(i=1)^(4)zi^(3) is

If z_(1),z_(2) are roots of equation z^(2)-az+a^(2)=0 then |(z_(1))/(z_(2))|=

Sum of common roots of the equations z^(3) + 2z^(2) + 2z + 1 =0 and z^(1985) + z^(100) + 1=0 is

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