Give your comments on the degree of $f\cdot g$ and $f+g$, with $f,g \in
\Fb[x]$
and prove them. \Fb[x]$.

As %
Since we
explained for multiples, can multiply polynomials, we can
underline that also
"raising raise them to
powers" is
an operation powers, with
peculiar properties, making this process different from the
analogous for polynomials over $\RR$. usual meaning
$$
f^n=\underbrace{f\cdots f}_n
$$
\\
Consider for example the polynomial $f(x)=x+1\in \Fb[x]$ and suppose to compute
its square power $(x+1)^2$. This means multiplying $f$ by itself so
