\(2016^{0^{2015}}+1\)=
G = 20160 + 20161 + 20162 + ... + 20162015
Tính 2015 .G +1
G= 2016^0+2016^1+2016^2+...+2016^2015
2016G=2016^1+2016^2+2016^3+...+2016^2015
2016G=(2016^0+2016^1+2016^2+2016^3+...+2016^2015)+2016^2016-2016^0
2016G=G+2016^2016-2016^0
2016G-G=2016^2016-2016^0
2015G=2016^2016-2016^0
2015G=2016^2016-2016^0/2015
G = 2016^0 + 2016^1 + 2016^2 + ... + 2016^2015
2016G = 2016^1 + 2016^2 + 2016^3 + ... + 2016^2016
2016G - G = 2016^2016 - 2016^0
2015G = 2016^2016 - 1
2015G + 1 = 2016^2016
a, |x - 2016| - x + 2016 = 0
b, |x - 2015| + x - 2015 = 0
-x+2016-x+2016=0
-2x-4032=0
-2x=4032
x=-2016
