perplexus.info :: Just Math : Digital power

Digital power (Posted on 2008-11-15)

Find all numbers N = a₁a₂a₃...a_n greater than 1, with no leading zeros, no zeros, which fits this equation:

N = a₁^a₁ + a₂^a₂ + a₃^a₃ + ... + a_n^a_n

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

re(2):2nd Solution : Zero to the zero power

(In reply to re:2nd Solution : Zero to the zero power by Ady TZIDON)

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.
