3. a) For any group G and any a∈G, prove that given any k∈Z+, C(a) ⊆ C(ak). (HINT: You are being asked to show that C(a) is a subset of C(ak). You can prove this by proving that if x ∈ C(a), then x must also be an element of C(ak) for any positive integer k.) b) Is it necessarily true that C(a) = C(ak) for any k ∈ Z+? Either prove or disprove this claim.
