abstract algebra - Question about centralizer and groups ...

Let $a$ be an ,element, of the group $G$, and define its centralizer as $$C(a)=\left\{x \in G : a*x=x*a \right\}$$ We already know that $C(a)$ defines a subgroup of $G$ but I'm supposed to prove that $C(a) = C(a^3)$ if $o(a)=5$ where $o(a)$ denotes the order of the ,element, $a$.

Centralizers of Elements in the Free Group - Mathematics ...

According to what I have been reading from various sources online, the centralizer of some element, $h \in F_n$,, denoted as $C_{F_n}(h)$, is an, infinite cyclic, group. Furthermore, every subgroup of $F_n$ is itself a free group, which would seem to suggest that $C_{F_n}(h)$ is a free group on one generator.

Although in type A each conjugacy class contains an ,element, w such that the normalizer complement NJ is also a ,centralizer, complement, this cannot be expected in general to be the case. However, from the preceding examples one Ã sees that it is frequently possible to construct from NJ an isomorphic copy NJ which Ã is a ,centralizer, complement.
