" If "x+" iy "=sqrt((3+4i)/(5+12i))" then "169(x^(2)+y^(2))^(2)=

If x+iy=sqrt((1+i)/(1-i)), prove that x^(2)+y^(2)=1

If x+ iy=(1+ 4i)(1+5i) , then (x^(2)+y^(2)) is equal to :

If x+ iy=(1+ 4i)(1+5i) , then (x^(2)+y^(2)) is equal to :

Select and write the correct answer from the given alternatives in each of the following: If (x + yi) (3 - 4i) = 5 +12i, then sqrt(x^2 + y^2) =

If x+iy=(1+i)(1+2i)(1+3i) , then x^(2)+y^(2) equals:

If (x+iy)(3-4i) = 5+12i , then sqrt(x^2+y^2) =

x+iy=(1-i sqrt(3))^(100), then (x,y)=

If ((1+i)^2)/(2-i)=(x+iy)" then "x+y =

If (1+2i) (2+3i)(3+4i)=x+iy,x,y in R then x^(2)+y^(2) is
