Abstract
In this paper, we introduce seventh- and sixth-order methods for solving the systems of nonlinear equations. The convergence analysis of the proposed methods is provided. The computational efficiency for these methods is \( 6^{1/(3n+2n^2)} \) and \( 7^{1/(4n+2n^2)} \). Computational efficiency of new methods is compared with Newton’s method and some other recently published methods. Numerical examples are included to demonstrate the validity and applicability of the methods and comparison is made with the existing results.
