The Root Test is a method used to determine the convergence or divergence of an infinite series. Specifically, it helps assess the behavior of a series of the form: \\\[ \\sum_\{n=1\}^\{\\infty\} a_n \\\] where \\( a_n \\) is a sequence of real or complex numbers. The primary approach is based on the concept of the \\( n \\)-th root of the absolute value of the terms in the series.
