Construct a unique simple submodule

[QUOTE="TMO, post: 6031390, member: 202286"] [B]Problem.[/B] Let ##p## be a prime integer. Let ##Z_p^\infty## be the set of complex numbers having order ##p^n## for some ##n \in \mathbb{N}##, regarded as an abelian group under multiplication. Show that ##Z_p^\infty## has an unique simple submodule. [B]Attempted solution.[/B] The collection of all elements of order ##p## of ##Z_p^\infty## has the structure of an abelian cyclic group. Now how do I also show that it is closed under scalar multiplication? Would showing that it is closed under scalar multiplication suffice to prove that it is a submodule? [/QUOTE]
