Express `{(x, y) x^2 + y^2 =100`, where x, `y in w`} as a set of ordered pairs.

Express ((x,y) such that x^2+y^2=25 where, x,y in W} as a set of ordered paires.

If x - y = 10 and x = 2y, then

If [frac{3}{2}+i frac{sqrt3}{2}]^50 = 3^25(x-iy) ,where x,y are real and i=sqrt(-1) , then the order pair (x,y) is given by

If x+2i+15i^6y = 7x+i^3(y+4) , where x,y in R, then x+y =

If (x _(1), y_(1))and (x_(2), (y_(2)) are the end points of a focal chord of the parabola y ^(2) = 5x, then 4 x _(1) x_(2)+y_(1)y_(2)=
