Showing that $a$ is a primitive root modulo $p$

Any element of $\mathbf{Z}[\xi]$ is congruent to an integer modulo $(1-\xi)^2$ if multiplied by a suitable power of $\xi$

If $p$ is an odd prime and $k$ an integer with $0<k<p-1$ then $1^k + 2^k + \ldots + (p-1)^k$ is divisible by $p$

What are primitive roots modulo n?

2 is a primitive root mod $3^h$ for any positive integer $h$

Prove if $n$ has a primitive root, then it has exactly $\phi(\phi(n))$ of them

Do there exist general conditions for cyclicity of unit groups of quotient rings (generalizations of the primitive root theorem)?

Does the expression $x^4 +y^4$ take on all values in $\mathbb{Z}/p\mathbb{Z}$?
