已知实数x,y满足下x^2+根号2y=根号3,y^2+根号2x=根号3,求x/y+y/x

已知实数x,y满足下x^2+根号2y=根号3,y^2+根号2x=根号3,求x/y+y/x 已知实数x.y满足根号(x+y-8)+根号(8-x-y)=根号(3x-y-4)+根号(x-2y+7),求x,y 代数式求值.已知x=2,y=根号3,求 (根号x-根号y)/(根号x+根号y)+(根号x+根号y)/(根号x-根号y) 已知正实数x y满足x-根号xy-2y=0求 x+3根号xy+2y/2x-2根号下xy-y (1/2)已知实数x,y,a满足：根号(x+y-8)+根号(8-x-y)=根号(3x-y-a)+根号(x-2y+a+3) 已知实数x.y满足根号x+y-8+根号8-x-y=根号3x-y-a+根号x-2y+a+3 已知x、y为实数,且根号x²=根号3-根号2,根号y平方=根号2,x+y≠根号3,求x-y 已知y=根号1-x+根号x-1+3,求根号x+根号y分之x+2根号xy+y+根号x-根号y分之一的值 已知实数x,y满足(x-根号下[x平方-2013])X(y-根号下[y平方-2013])=2013则3(x平方)-2(y x y a满足根号下x+y-8+根号下8-x-y=根号下3x-y-a+根号下x-2y+a+3 已知实数x,y满足根号[4x-y+11]+根号[1/3y-4x-3]=0,求2x根号[x/y]*1/2y根号[y^2/x 已知实数x、y满足x的平方+（根号2）y=根号3,y的平方+（根号2）x=根号3,且x不等于y,求x/y+y/x?
