若x+y=3m,x-y=n/3,则x^4+y^4-2x^2y^2=若x+y=3m,x-y=n/3,则x^4+y^4-2x^2y^2=若x+y=3m,x-y=n/3,则x^4+y^4-2x^2y^2=x
若x+y=3m,x-y=n/3,则x^4+y^4-2x^2y^2=
若x+y=3m,x-y=n/3,则x^4+y^4-2x^2y^2=
若x+y=3m,x-y=n/3,则x^4+y^4-2x^2y^2=
x^4+y^4-2x^2y^2=(x²-y²)²=(x-y)²(x+y)²=m²n²
x^4+y^4-2x^2y^2=(x^2-y^2)^2=[(x+y)(x-y)]^2
=(3m*n/3)^2=(mn)^2=m^2n^2
(X+Y)*(X-Y)=X^2-Y^2=mn
(X^2-Y^2)^2=X^4+Y^4-2X^2Y^2=M^2N^2
若x^3y^m-1*x^m+n*y^2n+2=x^9y^9,则4m-3n=().
