请楼主仔细看下我的答案是否正确,如果就是看不明白我也没办法,不过可以Hi我.
2^100 + 2^97 - 2 = 2[2^96 - 1] + 2^100
= 2[1 + 2 + 2^2 + ...+ 2^95] + 2^100
= 2 + 2^2 + 2^3 + ...+ 2^96 + 2^100
1*2 = 2
2 + 2 + 2 = 2 + 2^2
2 + 2^2 + 2 + 2 + 2 + 2 = 2 + 2^2 + 2^3
...
2 + 2^2 + 2^3 + ...+ 2^95 + 2 + 2 + ...+ 2 [ 2^95 个 2相加]
= 2 + 2^2 + 2^3 + ...+ 2^95 + 2^96
2 + 2^2 + 2^3 + ...+ 2^96 + 2 + 2 + ...+ 2 [2^99 个2相加]
= 2 + 2^2 + 2^3 + ...+ 2^96 + 2^100
