The value of (z+3)(bar(z)+3) is equivalent to

The value of (z+3)( bar z +3) is equivalent to

Write the value of arg(z)+arg(bar(z))

The equation z^(3)=bar(z) has

If |z| = 1, then the value of (1+z)/(1 +bar(z)) .

Let |z_(1)|=1, |z_(2)|=2, |z_(3)|=3 and z_(1)+z_(2)+z_(3)=3+sqrt5i , then the value of Re(z_(1)bar(z_(2))+z_(2)bar(z_(3))+z_(3)bar(z_(1))) is equalto (where z_(1), z_(2) and z_(3) are complex numbers)

If bar(z)=-3+5i" "then" z=

If |z|=1 then the maximum value of |z+bar(z)|^(2) is

If |z|=1 then the maximum value of |z+bar(z)|^(2) is

If |z|=3 then ((9+z)/(1+bar(z))) equals (A) z(B)bar(z) (C) 3z(D)z+bar(z) equals (A) z(B)bar(z)
