2016x20172017-2017x20162016

2016x20172017-2017x20162016 =2016x20172017-2017x10001x2016 =2016x20172017-20172017x2016 =2016x(20172017-20172017) =2016x0 =0

原式=2016×(2017×10001)-2017×(2016×10001)=0

2017x20162016—2016x2017 =2017x2016×10001—2016x2017 =2017x2016×(10001—1) =2016x2017×10000 =40662720000

2016x2017一2015x2015 =2016x(2015+2)-2015x2015 =2016x2015+2016x2-2015x2015 =(2016-2015)x2015+4032 =1x2015+4032 =2015+4032 =6047

答案是1. 题意是2017²-(2017-1)×(2017+1)=2017²-(2017²-1²)=2017²-2017²+1²=1

2017 =2016-1-2015/2017x(2017-2) =2016/解:原式=2016/2017x2 =2016-4032/2017x2015 =2016/2017 =2014又2/2017x2017-2016/2017 分析

解:2019X2018-2018X2017-2017x2016+2016x2015 =2018*(2019-2017)-2016*(2017-2015) =2018*2-2016*2 =2*(2018-2016) =2*2 =4

2015平方加2016平方加2017平方减2015x2016减2016x2017减2015x2017 =2015^2+2016^2+2017^2-2015x2016-2016x2017-2015x2017 =2015^2-2015x2016+2016^2-2015x2017+2017^2-2016x2017 =(2015-2016)x2016+2016^2-(2016-1)(2016+1)+(2017-2016)x2017 =-...

解答如下: 这是一道简单的一元一次方程求解题吗,虽然数字看起来很大,但是实际却很简单,求解如下 -2016x=-2015x-2017 解: 2017=2016X-2015X 2017=X(2016-2015) X=2017 即方程-2016x=-2015x-2017的解为2017
