In this question, k is defined independent to the definition of k in other questions. However, it is still true that k: (NXNXN) N. It is also true that k only involves the nested application of function g as defined in the aleph null module. Given that k((5,9, 7)) = 4287, step-by-step reason out the actual definition of k as a nested application of g. In this question, k is defined independent to the definition of k in other questions.
