Verbal subgroup of abelian group implies divisibility-closed

From Groupprops

This article gives the statement and possibly, proof, of an implication relation between two subgroup properties. That is, it states that every subgroup satisfying the first subgroup property (i.e., verbal subgroup of abelian group) must also satisfy the second subgroup property (i.e., divisibility-closed subgroup)

Statement

Suppose is an abelian group and is a verbal subgroup of (so is a verbal subgroup of abelian group). Then, is a divisibility-closed subgroup of . In other words, for any prime number such that is -divisible, is also -divisible.

Facts used

  1. Verbal subgroup equals power subgroup in abelian group

Proof

The proof follows from Fact (1) and a little more work. PLACEHOLDER FOR INFORMATION TO BE FILLED IN: [SHOW MORE]
