a = 2014100 - 201499 = 201499(2014 - 1) = 201499.2013
b = 201499 - 201498 = 201498(2014 - 1) = 201498.2013
Vì 201499.2013 > 201498.2013 => a > b
A= 2014^100 - 2014^99 = 2014^99 ( 2014 -1) = 2014^99 . 2013
B = 2014^99 - 2014^98 = 2014^98 ( 2014 - 1) = 2013.2014^98
Vì 2014^98 <2014^99 > 2013.2014^98 < 2013.2014^99
=> B < A
