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:

Is it true that square root of any positive integer greater than one, which is not a perfect square, is an irrational number?

This question was raised during a discussion with first year degree students.  The motivation was the proof showing the  irrationality of  $\sqrt{2}$.  The discussion took us to the following 'one line' proof: If $n$ is such a number having the rational expression $\sqrt{n}=\frac{a}{b}, \gcd(a,b)=1$, then by the fundamental theorem of arithmetic (unique prime factorization)  $b=1$ and $n$ is a square.
