(x+根号(x^2+4))(y+根号(y^2+2))=16 求x根号（y^2+2)+y根号（x^2+4)
已知4x^2+y^2-4x-6y+10=0,求(2\3x根号9x+y^2根号x/y^3)-(x^2-5x根号y\x) 拜
化简求值：x/x-y*y^2/x+y-x^4y/x^4+y^4÷x^2/x^2+y^2其中x=根号2,y=-1 ②：（a

x^2+4y^2-6x+4y+10=0,求x^4-y^4/(x+2y)(x-2y)*x+2y/xy^2+y^3除以（x^
已知(4x-y-1)^2+根号x+y-2=0,求4x^2y-4xy+xy^2
计算题 (2x-y)^2-(4x+y)(y-4x)
已知4x^2+y^2-4x-6y+10=0,求(2\3x根号9x+y^2根号x/y^3)-(x^2根号（1\x）-5x根
1）已知x^2+y^2-2x+4y+5=0,求x^4-y^4/(x+y)(2x-y)`2x-y/x
已知x^2+4y^2-4x+4y+5=0,求(x^4-y^4/2x^2+xy-y^2)*(2x-y/xy-y^2)/(x
