11. A subgroup H of a group G is called normal if for all r E G, the left coset rG is equal to the right coset Gr. In each of the following cases, define whether H is a normal subgroup of G You do not need to show it is a subgroup. (a) G-S3, H e, (1,2)) (b) G = GL(2, R) (with operation matrix multiplication); H = (c) G-U(Z2s) (with operation multiplication modulo 24); H-1,11

Question 2.

How do I do these linear algebra questions?
The question is:
Consider the Vector Space V and its subset W given below.
Determine whether W forms a subspace of V. If your answer is
negative then you must provide which subspace requirement is
violated.
(b). V is P5, the vector space of all polynomials in x of degree s5 and W is the set of all polynomials divisible by x – 3. (c). V is P5, the vector space of...
