设非零复数x,y满足x^2+xy+y^2=0.则代数式[x/(x+y)]^2010-[y/(x+y)]^2010=?

设非零复数x,y满足x^2+xy+y^2=0.则代数式[x/(x+y)]^2010-[y/(x+y)]^2010=? 设非零复数x,y满足x^2+xy+y^2=0,求代数式（x/x+y）^1990+(y/x+y)^1990的值 一道高中复数四则运算题目我不太懂,设非零复数x,y满足x^2+xy+y^2=0,则代数式[ x/(x+y)]^2010+[ y/(x+y)]^2010的值是多少? 已知实数xy满足x+2y 已知实数xy满足 x+y-2 正数x,y满足x-y=2xy,求x-y/x+y的值. 已知xy满足约束条件y=2 2X+y 已知x.y满足X2-y2=2xy.则x-y/x+y=?x. 若实数x,y满足x^2-xy-y^2 =0,则x/y=? 整数x,y满足方程2xy+x+y=83,则x+y怎么算 若正实数x.y满足x+y=xy,则x+2y的最小值 整数x,y满足x2-y2=2xy,求x-y/x+y的值 已知正整数x,y满足：xy-x-y=0,则x+2y的最小值 若正整数X,Y满足2X+Y--XY=0,求X+Y的最小值 正整数x,y满足x2-y2=2xy,求x-y/x+y的值 x,y满足2xy+x+y=83.x+y是何数? 已知正数x,y满足2x+8y-xy=0,x+y的最小值 若xy满足x²+2x+y-2√y-1=-1,求xy,
