Could you please explain how to show this in detail? I don't understand if it is too concise... 

**Problem 7.**

Let \( G \) be a group of odd order. Show that for all \( a \in G \) there exists \( b \in G \) such that \( a = b^2 \).

*Explanation:*

This problem explores a property of groups in abstract algebra, specifically involving elements and their squares in a group of odd order. The goal is to demonstrate that every element \( a \) in the group \( G \) can be expressed as the square of some element \( b \) from the same group. 

Approach this by considering the properties of group elements, potential symmetry, and using the fact that the order of the group is odd.
