L(a) =a^2 and M(a)= a mod 5 for each integer a

**Function Definitions and Problem Solving**

Define the functions \( L: \mathbb{Z} \rightarrow \mathbb{Z} \) and \( M: \mathbb{Z} \rightarrow \mathbb{Z} \) by the rules:
- \( L(a) = a^2 \) 
- \( M(a) = a \mod 5 \) for each integer \( a \).

**Task (a):** Find the following values:
1. \( (L \circ M)(16) = \) 
2. \( (M \circ L)(16) = \) 
3. \( (L \circ M)(13) = \) 
4. \( (M \circ L)(13) = \) 

**Task (b):** Determine if \( L \circ M = M \circ L \). Choose:
- Yes
- No
