A **perfect power** is a positive integer that can be expressed in the form \\( n = a^k \\), where \\( a \\) is a positive integer and \\( k \\) is an integer greater than 1. In other words, a number is a perfect power if it can be represented as an integer raised to an integer power greater than one. For example: - \\( 4 \\) is a perfect power because \\( 4 = 2^2 \\).
