Question

10.3.4·This exercise shows that the center of An is trivial for all n 4. (a) Compute that the center of A4 is se) (b) Show that for n 2 4, An is not abelian. (c) Use Exercise 10.3.3 and Theorem 10.3.2 to show that if n 5, then the center of An is either {e) or An. Since An is not abelian, the center is se).

You don't need to prove 10.3.3 or the theorem 10.3.2. You just need to answer the 10.3.4 part (c) by using 10.3.3 and 10.3.2.
