A= - 2014 +2014 +1 . (-1) +(- 8) - 12/25 - 17/37 +13/25 - 20/37
A = ( -2014+2014) + ( - 1) +(-8) - (12/25 - 13/25 ) - (17/37 +20/37)
A = 0 +(-1) + (-8) +1/25 -1
A =(-9) +0,04 - 1
A = - 9,96

1. \(G=2016.2016=\left(2014+2\right)\left(2018-2\right)=2014.2018-4028+4036-4=2014.2018+4\)
vì 2014.2018+4 >2014.2018
=> G>H
\(\frac{2016.2016}{2013.2019}=\frac{\left(2013+3\right)\left(2019-3\right)}{2013.2019}=\frac{2013.2019-6039+6057-9}{2013.2019}=\frac{2013.2019+9}{2013.2019}=1+\frac{9}{2013.2019}\)
vì \(1+\frac{9}{2013.2019}>1\)
\(\frac{2016.2016}{2013.2019}>1\)
