Abstract

            This research was to examine some forms of composite numbers by using the Nelsen’s proof (2021), which has previously shown that gif.latex?n^{4}+4^{n} was composite forgif.latex?n&space;\geq2. The results reveal that forgif.latex?m,n,k\in&space;\mathbb{N},


1) if  was even, then gif.latex?n^{4k}+4^{m} and gif.latex?9^{n}+\frac{\left&space;(&space;kn&space;\right&space;)^{4}}{4} were composite,


2) if gif.latex?m,n were odd and gif.latex?mn\neq&space;1, then gif.latex?n^{4k}+4^{m} was composite.
