Let z=9+ai, where `i=sqrt(-1)` and a be non-zero real.
If `Im(z^(2))=Im(z^(3))`, sum of the digits of `a^(2)` is

Let z=9+bi where b is non zero real and i^(2)=-1. If the imaginary part of z^(2) and z^(3) are equal,then b^(2) equals

if |z-i Re(z)|=|z-Im(z)| where i=sqrt(-1) then z lies on

If Im((z-1)/(2z+1))=-4, then locus of z is

if (Im(z))^(2)=4(Re(z)-2) then arg(z)canbe

If Im((z-i)/(2i))=0 then the locus of z is

if Im((z+2i)/(z+2))= 0 then z lies on the curve :

If "Im"(2z+1)/(iz+1)=-2 , then locus of z, is
