Re: chess board sum

Hi yuvaraj 358;

Welcome to the forum.

If I understand the problem correctly, I think the answer is 2^(2^63).

Some facts about the answer (according to WolframAlpha):

(a) It = 2^9223372036854775808.

(b) It = 10^(10^18.44349949917649).

(c) It's 2776511644261678567 decimal digits long.

(d) Its last ten digits are 1456608256.
