If x -iy = frac{a-ib}{c-id} , then prove that ( x^2 + y^2 ) = frac{a^2+b^2}{c^2+d^2}

If (a + ib) (c + id) (e + if) (g + ih) = A + iB , then show that (a^2 + b^2) (c^2 + d^2) (e^2 +f^2) (g^2+ h^2) = A^2 + B^2

If sqrt(3)+i=(a+ib)(c+id), then find the value of tan^(-1)(b/a)+tan^(-1)(d/c)

If x+iy=sqrt((a+ib)/(c+id)) , then find the value of x^(2)+y^(2) .

If x+iy=sqrt((a+ib)/(c+id)), then write the value of (x^(2)+y^(2))^(2)

If p+iq = sqrt(frac{a+ib}{c+id}) , then p,q,a,b,c,d in R, then (p^2+q^2)^2 =
