If `x+i y=sqrt((a+i b)/(c+i d)),` then write the value of `(x^2+y^2)^2`.

If x" - "i y" "=sqrt((a-i b)/(c-i d)) prove that (x^2+y^2)^2=(a^2+b^2)/(c^2+d^2)

If x" - "i y" "=sqrt((a-i b)/(c-i d)) prove that (x^2+y^2)^2=(a^2+b^2)/(c^2+d^2)

If x+i y=sqrt((a+i b)/(c+i d)) prove that (x^2+y^2)^2=(a^2+b^2)/(c^2+d^2)

If x - i y =sqrt((a-i b)/(c-i d)) prove that x^2+y^2=(a^2+b^2)/(c^2+d^2)

(i) If x-iy = sqrt((a-ib)/(c-id)) prove that (x^(2) + y^(2)) =(a^(2) + b^(2))/(c^(2) + d^(2))

If x+i y=sqrt((a+i b)/(c+i d)) then (x^(2)+y^(2))^(2)=

If sqrt(a+i b)=x+i y ,\ then possible value of sqrt(a-i b) is a. x^2+y^2 b. sqrt(x^2+y^2) c. x+i y d. x-i y e. sqrt(x^2-y^2)

If x=2+3i and y=2-3i then find the values of : (x^(2)+xy+y^(2))/(x^(2)-xy+y^(2))

If x + i y =(a+i b)/(a-i b), prove that x^2+y^2=1 .
