Abstract
Let be an odd prime and let be a rational p-adic integer. In this paper we reveal the connection between quartic residues and the sum , where is the greatest integer not exceeding . Let be a prime of the form and so with . When , we show that for , if and only if where is the Legendre symbol. We also establish congruences for in the cases .
