If a,b,x,y are real and 3sqrt(x+iy)=a+ib show that , 3sqrt(x-iy)=a-ib

If a,b,x,y are real and 3sqrt(x+iy)=a+ib show that , 3sqrt(x-iy)=a-ib (x)/(a)+(y)/(b)=4(a^(2)-b^(2)).

If sqrt(a+ib)=x+iy then prove that sqrt(a-ib)=x-iy

If sqrt(a-ib) = x-iy , prove that sqrt(a+ib) =x+iy.

If sqrt(x+iy)=+-(a+ib), then find sqrt(-x-iy)

If (x+iy)^((1)/(3))=a+ib where x,y,a,b are real numbers such that (x)/(a)-(y)/(b)=k(a^(2)+b^(2)) then the value of k is

If (x+iy)^(1/3)=a+ib , where a,b,x, y in R, show that x/a-y/b=-2(a^2+b^2) .

If sqrt(x+ iy) = pm (a + ib) then sqrt(x-iy) =

If (x+iy)^(1//3) = a+ib , where a, b, x, y in R show that x/a - y/b = -2(a^(2) + b^(2)) .

If a,b,c,d,x,y are real and (a+ib)(c+id)=x+iy, show that , (a-ib)(c-id)=x-iy
