If x y 25 and x 2y 3 y 2x 3 25 what is the value of xy

x^2*y^3 + y^2*x^3=25
=> x^2*y^2*(y+x)=25
=> x^2*y^2*25=25 [given, x+y=25]
=> (xy)^2 = 1
=> xy = 1

x2y3+x3y2=25
x2y2(x+y)=25
x2y2=1
xy=1

answer is 1
x2y2(x + y ) = 25
hemce xy = 1

x2y3+x3y2=25
x2y2(x+y)=25
x2y2=1
xy=1

x2y2(x+y)= 25
(xy)^2= 1
so, xy= +1 or -1

1 is the ans

since x+y= x^6y +y^6x thus 6x=6y=1
x=y=1/6
thus xy =1/36

1 is answer

from second eq. x^2*y^2 is taking common
so x^2*y^2(y+x)=25
(xy)^2=25/25
xY=1,-1

(x^2)(y^3)+(y^2)(x^3)=25
(x^2)(y^2)(x+y)=25
(x^2)(y^2)=1
xy=1
