\newpage \sectionThe Sylow Theorems \beginproblem[4.5.17] Prove that if $|G| = 105$ then $G$ has a normal Sylow 5-subgroup and a normal Sylow 7-subgroup. \endproblem \beginsolution Let $G$ be a group of order $105 = 3 \cdot 5 \cdot 7$. Let $n_5$ be the number of Sylow 5-subgroups. By Sylow's theorems, $n_5 \equiv 1 \pmod5$ and $n_5$ divides 21. The possibilities are $n_5 = 1$ or $21$. We will show that $n_5 = 1$ is forced. \endsolution dummit+and+foote+solutions+chapter+4+overleaf+full
