已知根号x-y+根号x-y-2=0求实数xy的值

已知根号x-y+根号x-y-2=0求实数xy的值 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 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 已知实数X,Y满足根号2X-Y-8+根号X+2y+1=0,求XY. 已知x+y-2根号下x-4根号下y+5=0,求实数x,y的值 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 已知4x2+9y-4x-6y+2=0 求根号y/根号x+根号y - 根号y/根号x-根号y快. 已知4x2+9y-4x-6y+2=0 求根号y/根号x+根号y - 根号y/根号x-根号y急用. 已知x,y为实数,且y=根号2x-6+根号(3-x)+1,求x根号2x÷根号x/y 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y=根号x-1+根号1-x+8求根号x+y.的平方根 已知x+y+13-4倍根号x-6倍根号y=0,求实数x,y的值? 已知,4根号x+6根号y-13-x-y=0,求实数x和y的值. 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x,y为实数,且根号x+x+根号y+y=0,则代数式根号x^5y 已知根号4x-1+根号y+2=0,求根号x-y的值 已知x>0,y>0根号x(根号x+2倍根号y)=根号y(6倍根号x+5倍根号y)求:(x + 根号xy - y)/(2x + 根号xy +3y) 的值
