So sánh 2017^2016+2018/2017^2017+2018với 2017^2017+2018/2017^2018+2018
Ai kết bạn mình đi
So sánh: A=(20182017 +20172017)2018 và B=(20182018+20172018)2017
A=2017^2018+1/2017^2018-3
B=2017^2018-1/2017^2018-5
so sánh : P = 2016/2017 + 2017/2018 + 2018/2019 và Q = 2016 + 2017 + 2018/2017 + 2018 + 2019
So sánh:
A= 2018^2017+1/2018^2017-1
B= 2018^2017-1/2018^2017-3
( 2016 * 2017 + 2018 * 2 + 2015 ) : [ ( 2018 : 2017 - 2017 * 2015 ) + 2016 ]
