First, we determine the entire family of positive integer solutions to the three- variable Diophantine equation, xy=z^2; for n=2,3,4,5,6. For n=2, we obtain a 3-parameter family of solutions; for n=3, a 5-parameter of solutions; likewise for n=4. For n=5, a 7-parameter family of solutions; and likewise for n=6. See Theorems 2 through 6 respectively. The second goal of this paper, is determining all the positive integer solutions of xyz=w^2. This is done in Theorem7; the solution set is described in terms of six independent parameters. Finally, in Theorem 8, we achieve our third goal: determining all the positive integer solutions of the 5-variable Diophantine system: xy=v^2 and yz=w^2. The solution set is expressed in terms of eight parameters. This paper contains a total of four references.", "revisions": [ { "version": "v1", "updated": "2013-07-17T21:22:33.000Z" } ], "analyses": { "keywords": [ "diophantine system", "positive integer solutions", "solution set", "paper contains", "third goal" ], "note": { "typesetting": "TeX", "pages": 19, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013arXiv1307.5328Z" } } }
