find x,y from the equation:  (1/2)x−yi+(1/(1+i))=((√(1+ω^8 ))+(√(1+ω^(10) )))^4
findx,yfromtheequation:12xyi+11+i=(1+ω8+1+ω10)4

⇒  (x/2)−iy+((1−i)/2)=((√(−ω))+(√(−ω^2 )))^4   (x/2)−iy=((−1+i)/2)+(e^(−((iπ)/6)) +e^((iπ)/6) )^4   (x/2)−iy=((−1+i)/2)+9  ⇒    x=17  ;  y=−(1/2) .
x2iy+1i2=(ω+ω2)4x2iy=1+i2+(eiπ6+eiπ6)4x2iy=1+i2+9x=17;y=12.
