Sta su even numbers (parni valja)?
Sta je aliquot part nekog broja?
Kako prevesti ovo:Whether the five assertions of Nicomachus were based on any more than this algorithm and the fact the there were four perfect numbers known to him 6, 28, 496 and 8128, it is impossible to say, but it does seem unlikely that anything more lies behind the unproved assertions.Some of the assertions are made in this quote about perfect numbers which follows the description of the algorithm ?
