2/y(根号xy^5)*(-3/2根号x^3 y)除以1/3根号y/x
【(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-
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)
已知y=根号1-x+根号x-1+3,求根号x+根号y分之x+2根号xy+y+根号x-根号y分之一的值
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)
5x根号xy除以3根号x分之y乘以3分之1根号y分之x(x>0)
已知x,y为正数,且根号x(根号x+根号y)=3根号y(根号x+5根号y),求:(2x+根号xy+3y)/(x+根号xy
设x>0,y>0,且根号x(根号x+根号y)=3根号y(根号x+5根号y),求代数式2x+根号xy+2y\x-根号xy-
若x>o,y>o,且根号x(根号x+根号y)=3根号y(根号x+5根号y)求x+根号xy分之2x-根号xy-5y
化简:5根号X^3Y-2Y根号XY-6根号XY+根号X分之Y+根号Y分之X
已知x平方+y平方-2y+1=0,求(根号x+根号y+3)/((根号xy+y)(3根号x+根号y))
根号X(根号X+根号Y)=3根号Y(根号X+5根号Y),求(X+根号XY-Y)分之(2X+根号XY+3Y)的值
根号X(根号X-根号Y)=3根号Y(5根号Y-根号X),求(2X-根号XY+3Y)/X+根号XY-6Y
