If `ahati+bhatj+chatk` be a unit vector and z is a comple number such that `(1+a)z=b+ic, then (1-iz)/(1+z` (A) `(a+ib)/(1+z)` (B) `(1+c)/(a+ib)` (C) `(a+ib)(1+c)` (D) none of these

If ahati+bhatj+chatk be a unit vector and z is a complex number such that (1+a)z=b+ic, then (1-iz)/(1+z (A) (a+ib)/(1+z) (B) (1+c)/(a+ib) (C) (a+ib)(1+c) (D) none of these

If z = a+ib is a complex numbers, then

If z = a+ib is a complex numbers, then

If z(1+a)=b+i c and a^2+b^2+c^2=1, then [(1+i z)//(1-i z)= A. (a+i b)/(1+c) B. (b-i c)/(1+a) C. (a+i c)/(1+b) D. none of these

If a,b,c are real numbers and z is a complex number such that,a^(2)+b^(2)+c^(2)=1 and b+ic=(1+a)z then (1+iz)/(1-iz) equals.(a) (b-ic)/(1-ia) (b) (a+ib)/(1+c) (c) (1-c)/(a-ib)( d) (1+a)/(b+ic)

If z(1+a)=b+icanda^(2)+b^(2)+c^(2)=1 then [(1+iz)/(1-iz)=(a+ib)/(1+c) b.(b-ic)/(1+a)c(a+ic)/(1+b) d.none of these

If (x+iy)^(1/3)=a+ib, then (x)/(a)=(y)/(b)=0b1c.-1d .none of these

If z_1=a+ib and z_2=c+id are two complex numbers then z_1 gt z_2 is meaningful if
