A = 2016 . 2018
= ( 2017 - 1 ) . ( 2017 + 1 )
= 2017 . 2017 + 2017 - 2017 - 1
= 2017 . 2017 - 1
Vì 2017 . 2017 < 2017 . 2017 nên A < B
Ta có : A = 2016 . 2018
= (2017 - 1)(2017 + 1)
A = 20172 - 1 < 20172
Vậy A < B .
A=2016.2018
=(2017-1)(2017+1)
=2017.2017+2017-2017-1
=2017.2017-1
Vì 2017.2017<2017.2017
=>A<B
A = 2016 . 2018
= (2017 - 1)(2017 + 1)
A = 20172 - 1 < 20172
Vậy A < B .
