已知x=2,y=3,求代数式(x-y)*(x-y)^3*(x-y)^5*……*(x-y)^11已知x=2,y=3,求代数式(x-y)*(x-y)^3*(x-y)^5*……*(x-y)^11已知x=2,

已知x=2,y=3,求代数式(x-y)*(x-y)^3*(x-y)^5*……*(x-y)^11
已知x=2,y=3,求代数式(x-y)*(x-y)^3*(x-y)^5*……*(x-y)^11

已知x=2,y=3,求代数式(x-y)*(x-y)^3*(x-y)^5*……*(x-y)^11
x-y=2-3=-1
所以
(x-y)*(x-y)^3*(x-y)^5*……*(x-y)^11
=(-1)*(-1)² *(-1)² *.(-1)^11=-1*1*(-1)...(-1)=(-1)^6 *1^5=1

(x-y)=-1
则(x-y)*(x-y)^3*(x-y)^5*……*(x-y)^11=(-1)^6=1
