Vedclass · Answer

(A) Given $x + iy = \sqrt{\frac{a + ib}{c + id}}$.Taking the conjugate on both sides,we get $x - iy = \sqrt{\frac{a - ib}{c - id}}$.Now,multiplying these two equations:$(x + iy)(x - iy) = \sqrt{\frac{a + ib}{c + id}} 	imes \sqrt{\frac{a - ib}{c - id}}$$x^2 + y^2 = \sqrt{\frac{(a + ib)(a - ib)}{(c + id)(c - id)}}$$x^2 + y^2 = \sqrt{\frac{a^2 + b^2}{c^2 + d^2}}$Squaring both sides,we get $(x^2 + y^2)^2 = \frac{a^2 + b^2}{c^2 + d^2}$.

If $x + iy = \sqrt{\frac{a + ib}{c + id}}$,then $(x^2 + y^2)^2 = $
