In this paper we compute the Waring rank of any polynomial of the form F=∑i=1rMi, where the M i are pairwise coprime monomials, i.e., GCD(M i, M j)=1 for i≠j. In particular, we determine the Waring rank of any monomial. As an application we show that certain monomials in three variables give examples of forms of rank higher than the generic form. As a further application we produce a sum of power decomposition for any form which is the sum of pairwise coprime monomials. © 2012 Elsevier Inc.
