2x-5y-4=0,求4^x÷32^y的值过程

若(x*x+y*y)(x*x+y*y)-4x*x*y*y=0,求代数式(x*x+5xy+y*y)/(x*x+2xy+y*y)的值 已知X.x+y.y-4x+2y+5=0,求4X.X-12X Y+9Y.y的值 已知x*x-4xy+4y*y=0 求[2x(x+y)-y(x+y)]/(4x*x-4xy+y*y)的值? x的平方-4x+y的平方+2y+5=0,求x+y 已知x+4y-2x+8y+5=0,求x^4-y^4/2x+xy-y·2x-y/xy-y÷(x+y/y)的值.数学上交不不算请教下. x²+y²-2x-4y+5=0 求 x,y的值 x平方+2x+y平方-4y+5=0求y的x方 已知X^2+Y^2-2X-4Y+5=0,求分式Y/X-X/Y的值 已知x²+y²-2x-4y+5=0,求分式y/x-x/y的值. 已知x、y满足x²+y²+2x-4y+5=0,求x、y的值 x+y+2x+4y+5=0,求代数式x/y+y/x的值 RT,若（√2x-y）+y^2+4y+4=0,求[(x-y)^2+(x+y)(x-y)]÷2x的值 已知5x-4y=0,求x:y和x+y:y的值 2x-5y-4=0,求4^x÷32^y的值过程 已知x-y=1,求[(x+2y)²+(2x+y)(x-4y)-3(x+y)(x-y)]÷y的值 已知x-2y=2011,求[(3x+2y)(3x-2y)-(x+2y)(5x-2y)]÷4x的值. x*x+4y*y+2x*x-4y+2=0求根号下5x*x+16y*y的值快啊 已知x²+4y²-4x+4y+5=0,求(2x-y)(x+y)/x四次方-y四次方×xy-y²/2x-y÷(y/x²+y²)²
