We study the -adic equation = over the field of -adic numbers. We construct an algorithm which gives a solvability criteria in the case of = and present a computer program to compute the criteria for any fixed value of ≤ − 1. Moreover, using this solvability criteria for = 2 3 4 5 6, we classify -adic 6-dimensional filiform Leibniz algebras.
