化简(x-y)/(根号x+根号y)化简(x-y)/(根号x+根号y)化简(x-y)/(根号x+根号y)(x-y)/(根号x+根号y)=((根号x)²-(根号y)²)/(根号x+根号
化简(x-y)/(根号x+根号y)
化简(x-y)/(根号x+根号y)
化简(x-y)/(根号x+根号y)
(x-y)/(根号x+根号y)
=((根号x)²-(根号y)²)/(根号x+根号y)
=(根号x-根号y)(根号x+根号y)(根号x+根号y)
=根号x-根号y
答案 根号x-根号y
x-y=(根号x+根号y)(根号x-根号y) 平方差公式
(x-y)/(√x+√y)
=[(√x)²-(√y)²]/(√x+√y)
=(√x+√y)(√x-√y)/(√x+√y)
=√x-√y
化简:(根号X/Y)+(根号y/x)
化简(x-y)/(根号x+根号y)
已知x=2y,化简:根号y/根号x -根号y -根号y/根号x +根号y
已知x =2y 化简(根号y/根号x -根号y )-(根号y/根号x +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)
化简x/(根号x+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)
关于二次根式的!(根号x+根号y分之根号x + 根号y-根号x分之根号y - x-y分之二倍的根号xy)除以(根号x分之一 - 根号y分之一)*(根号x+根号y)化简!
根号x+根号y分之x-y化简
根号X-Y加上根号Y-X 化简
化简:(根号x+根号y)分之(x+y) +【根号xy乘以(根号x+根号y)】 分之2xy还有一题:根号(xy) -根号(x/y)+根号(y/x)+根号(x/y+y/x+2)
{化简} [x+y/(根号x+根号y)]+[2xy/x·根号y+y·根号x]
化简x十Y/根号x十根号y十2Xy/x根号y十y根号x
化简 x+根号xy+y分之x根号x-y根号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).
已知x=2y,y=0,化简,根号y/(根号x-根号y)-根号y/(根号x+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)]
x+y/根号X-根号Y-2XY/X乘根号Y-Y乘根号X
