If `z_1=9y^2-4-10ix, z_2=8y^2-20i,` where `z_1=overline z_2,` then find `z=x+iy`

If z_(1)=2-i and z_(2)=-2+i , then Re((1)/(z_(1)overline(z_(2))))= . . . .

Find the real values of x and y for which z_(1)=9y^(2)-4-10ix and z_(2)=8y^(2)-20i are conjugate complex of each other.

If z_1 =-3+ixy, z_2 =x+y+4i and z_1 = barz_2 then find x and y .

If arg(z-1)=arg(z+2i), then find (x-1):y, where z=x+iy

If z = x iy , xy ne 0 satisfy the equation z^2 i overline z = 0 , then |z^2| equal to

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

If Re((z-1)/(2z+i))=1, where z=x+iy ,then the point (x,y) lies on a

If z_1=7+6i,z_2=2+2i and z_3=1-4i then find z_1-z_2+z_3

For x_1,x_2, y_1, y_2 in R , if 0
