(x√x+x√y)/(xy-y^2)-[x+√(xy)+y]/(x√x-y√y)
=[x(√x+√y)/[y(√x-√y)(√x+√y)]-[x+√(xy)+y]/{(√x-√y)[x+√(xy)+y]}
=x/[y(√x-√y)]-1/(√x-√y)
=(x-y)/[y(√x-√y)]
=(√x-√y)(√x+√y)/[y(√x-√y)]
=(√x+√y)/y

x根号x+x根号y/xy-y^2)-（x+根号xy+y/x根号x-y根号）y 化简:((根号x-根号y)^3+2x根号x+y根号y)/(x根号x+y根号y)+(3根号xy-3y)/(x-y) ①{（x+y）/（根号x+根号y）}+{2xy/根号xy（根号x+根号y）} {（x-y)/(根号x+根号y)}-(x+y-2倍根号xy)/(根号x-根号y)=? 化简:(x-y)除以(根号x+根号y)-(x-2根号xy+y)除以(根号x-根号y) 【(x-y)^3(x^1/2+y^1/2)^-3+3(x根号y-y根号x)】/(x根号x+y根号y)+(2xy根号xy- 跟号打不出来,所以用汉字,大家费点劲哈（（根号x/根号x+根号y）-（根号y/根号y-根号x）-（2根号xy/x-y）化简（y根号x+x根号y）/（xy-y²）-（x+根号xy+y）/（x根号x-y根号y）. 化简：[（x×根号x+x×根号y）/（xy-y²）]-[（x+根号下xy+y）/（x×根号x-y×根号y）] 已知y=根号(x-8)+根号(8-x)+18,求代数式[(x+y)/(根号x+根号y)]-2xy/(x根号y-y根号x) {化简} [x+y/(根号x+根号y)]+[2xy/x·根号y+y·根号x] (x+y)/(根号下x+根号下y)+2xy/(x根号下y+y根号下x)=______.
