Find solutions to both a&c
**Question (a):** Construct a nontrivial homomorphism  
\[ \phi: \mathbb{Z}_6 \to \mathbb{Z}_{15} \]

**Question (c):** Find the \( \text{Ker}\phi \)

**Explanation:**
This question asks you to construct a nontrivial homomorphism from the cyclic group \(\mathbb{Z}_6\) to the cyclic group \(\mathbb{Z}_{15}\) and to find the kernel of this homomorphism. A nontrivial homomorphism is one that is not the zero homomorphism. The kernel of a homomorphism \(\phi\) is the set of elements in the domain that map to the identity element of the codomain.
