Sums of bases-exponents positive integer powers
Abstract
We consider natural numbers that can be represented as sums of positive integer powers greater than 1, such that the set of bases coincides with the set of exponents. We address this issue by indicating some equalities and relations, defining some new integer sequences recently introduced in the OEIS, reporting some experimental results and showing some graphs regarding the obtained numbers.
