对于两个数,A=—2016×20172017,B=—2017×20162016,比...

a=-2016×20172017 =-2016×2017×10001 b=-2017×20162016 =-2017×2016×10001 ∴ a=b

a=-2016×20172017=-2016×2017×10001, b=-2017×2016×2016=-2017×2016×10001, 所以a=b

a=40666786272;b=40666788289;b>a

2016×20172017-2017×20162016 2016×(2017×10001)-2017×(2016×10001) =0

1-a=1-20142014/20152015=10001/20152015 1-b=1-20152015/20162016=10001/20162016 1-c=1-20162016/20172017=10001/20172017 因为2015201510001/20172017 所以 a

(201720172017-20172017-2017)/(201820182018-20182018-2018) =[2017×(100010001-10001-1)]/[2018×(100010001-10001-1)] =2017/2018

20172017x20172017-20162016x20162016 =(20172017+20162016)X(20172017-20162016) =40334033X10001 =403380664033

简便运算20162016×2017-2016×2017207 20162016×2017-2016×2017207 =2016*10001*2017-2016*2017*10001 =2017*2016*10001-2017*2016*10001 =0

=2018*2017*10001-2017*20172018 =2017*(20182018-20172018) =20170000

2017×20162016-2016×20172017 =2017×2016×10001-2016×2017×10001 =0
