  • Fourth order iterative methods for solving nonlinear equations 
    Comemuang, Chalermwut; Orosram, Wachirarak (มหาวิทยาลัยราชภัฏบุรีรัมย์, 2021-10)
    In this paper, we present two new iteration methods to find the solutions of nonlinear equations, which were developed from a concept of Obadah [10] and Taylor’s Series to estimate the second derivative. Analysis of its ...
  • On the Diophantine Equation 8^x+n^y=z^2 
    Orosram, Wachirarak; Comemuang, Chalermwut (มหาวิทยาลัยราชภัฏบุรีรัมย์, 2020-10-29)
    Let n be an positive integer with n=10(mod15). In this paper, we prove that (1,0,3) is unique non-negative integer solution (x,y,z) of the Diophantine equation 8^x+n^y=z^2, where x,y and z are non-negative integers.
