A GENERALIZATION OF FERMAT’S LAST THEOREM BY ALHAJI ALKALI* AND G. U. GARBA DEPARTMENT OF MATHEMATICS AHMADU BELLO UNIVERSITY, ZARIA A PAPER PRESENTED AT THE 45TH ANNUAL CONFERENCE OF MATHEMATICAL ASSOCIATION OF NIGERIA (MAN), VENUE: FEDERAL COLLEGE OF EDUCATION (TECHNICAL) GUSAU ZAMFARA STATE. 25TH – 29TH AUGUST, * Correspondence author:

ABSTRACT The Fermat last theorem states that there is no integer triple such that for In this paper we attempt to extend this result to integer quadruples. It is shown that is true for, and general formula for generating them is obtained.

INTRODUCTION Pierre Fermat ( ) wrote a hand written comment by the side while reading Dedekind book of Pythagoras triple that there is no integer triple, for which for. This was only known some years after Fermat death. There is uncertainty as to whether Fermat had the proof of this result. This result known as Fermat’s last theorem remain unsolved for about 500years until 1995 when Andrew Wiles in a 110-page paper was able to provide a proof of this long standing conjecture, see [2].

for any natural number if there exit integer quadruple for which general rule for obtaining all integer quadruple for which Also to investigate whether there is integer quadruple for which for where is a natural number

Preliminary results Proposition2.1 If is an integer quadruple, then any multiple of this is also an integer quadruple, that is for any integer n is also an integer quadruple Proposition 2.2 For any quadruple if and are both odd integers, then and can not both be even. Proposition 2.3 For any quadruple if and are odd then must be odd Proposition 2.4 For any quadruple if and are even then must be even..

THEOREM 3.1 For any integers and, if we choose, and, then. will satisfies then equation Proof: Since

CONCLUTION This investigation was also extended to integer quadruple for which, and values are obtained that satisfy this relationship. We are now in the process of obtaining interesting results in line with this paper. However we are unable to obtain integer quadruple for which. It seen to us that there are no such integer quadruples for which for, thus extending the Fermat’s last theorem on integer triples to integer quadruples.
