Question

give two examples To show that Z⁴ is not isomorphic to the Klein 4-group​

Answer 1

Step-by-step explanation:

The Klein four group is

Z2×Z2,

where Z2 is the cyclic group of 2 elements. In this group, every element has order at most 2, while in a cyclic group of order 4, two elements have order 4, hence they cannot be isomorphic.
