On generators of multiplicative group
Generators of multiplicative group \((\mathbb{Z}/2^{\alpha}\mathbb{Z})^*\)
The set of all unit elements in the cyclic group \(\mathbb{Z}/N\mathbb{Z}\) is a group under multiplication modulo \(N\) of order \(\phi(N)\), where \(\phi\) is the Euler-totient function. It is denoted by \((\mathbb{Z}/N\mathbb{Z})^*\).It is well known that \((\mathbb{Z}/N\mathbb{Z})^*\) is not always cyclic (Primitive element theorem) (See Chater 10, [1]). For example \((\mathbb{Z}/8\mathbb{Z})^*=\{1,3,5,7\}\) is not cyclic. \((\mathbb{Z}/2\mathbb{Z})^*=\{1\}\) and \((\mathbb{Z}/4\mathbb{Z})^*=\{1,3\}\) are trivially cyclic.
Question: Show that for \(\alpha\geq 3\), \((\mathbb{Z}/2^{\alpha}\mathbb{Z})^*\) is generated by \(-1\) and 5?
You may use the following sage code for validating the result: Reference: [1] T M Apostol, Introduction to Analytics Number Theory

Some rational thoughts on Irrationality.
Is it true that square root of any positive integer greater than one, which is not a perfect square, is an irrational number?
