Check the correct statementa)the identity ofa subgroup is the same as ...
Explanation:
a) The identity of a subgroup is the same as that of the group.
The identity element in a group is an element that when combined with any other element in the group, leaves the other element unchanged. A subgroup is a subset of a group that itself forms a group under the same operation. Since a subgroup is a subset of the group, it contains the same identity element as the group. Therefore, the identity of a subgroup is the same as that of the group.
b) The inverse of any element of a subgroup is the same as the inverse of the same regarded as an element of the group.
In a group, every element has an inverse, which when combined with the element gives the identity element. A subgroup is a subset of a group, so the inverses of the elements in the subgroup are the same as the inverses of those elements in the group. Therefore, the inverse of any element of a subgroup is the same as the inverse of the same element regarded as an element of the group.
c) The order of any element of a subgroup is the same as the order of the element regarded as a member of the group.
The order of an element in a group is the smallest positive integer n such that raising the element to the power of n gives the identity element. Since a subgroup is a subset of a group, the order of an element in the subgroup is the same as the order of that element in the group. Therefore, the order of any element of a subgroup is the same as the order of the element regarded as a member of the group.
d) All of the above.
Since all of the statements a), b), and c) are true, the correct statement is d) All of the above.
