您好:
(x/x+y+2y/x+y)×(xy/x+2y)÷(1/x+1/y)
=(x+2y)/(x+y)*xy/(x+2y)*xy/(x+y)
=x²y²/(x+y)²

[x/(x+y)+2y/(x+y)]×[xy/(x+2y)]÷(1/x+1/y)=x²y²/(x+y)²

题没写全吧
(x/(x+y)+2y/(x+y))×(xy/(x+2y))÷(1/x+1/y)
=(x+2y)/(x+y)×xy/(x+2y)÷((x+y)/xy)
=(x+2y)/(x+y)×xy/(x+2y)×xy/(x+y)
=x²y²/(x+y)²
(x/(x+y)+2y/(x+y))×(xy/(x+2y))÷(1/x+1/y)
=(x+2y)/(x+y)×xy/(x+2y)÷((x+y)/xy)
=(x+2y)/(x+y)×xy/(x+2y)×xy/(x+y)
=x²y²/(x+y)²
