设x=54321×54324,y=54323×54322,你能比较x与y的大小吗?

设x=54321×54324,y=54323×54322,你能比较x与y的大小吗?
设x=54321×54324,y=54323×54322,你能比较x与y的大小吗?

设x=54321×54324,y=54323×54322,你能比较x与y的大小吗?
x=54321×54324=54321×(54321+3)=54321^2+3*54321
y=54323×54322=(54321+2)×(54321+1)
=54321^2+3*54321+2
y-x=2
y>x

X=54321×54323+54321×1
Y=54323×54321+54323×1
∵54321<54323 ∴X<Y
