Digital power (Posted on 2008-11-15) Difficulty: 2 of 5
Find all numbers N = a1a2a3...an greater than 1, with no leading zeros, no zeros, which fits this equation:

N = a1a1 + a2a2 + a3a3 + ... + anan

Clarifying, N = 23 doesn´t work because 22 + 33 is equal to 31, not 23.

During review Charlie did make mention of 0^0.

My QuickBasic interprets 0^0 as equivalent to 1.
On the other hand my version of MS Excel offers #NUM!

For the purposes of this exercise I see no point in reviewing my prior post at this time but do note the value of your contribution to this discussion.
