- 45. Let . Prove or disprove that is a group with respect to the operation of intersection. (Sec. )arrow_forwardLet A={ a,b,c }. Prove or disprove that P(A) is a group with respect to the operation of union. (Sec. 1.1,7c)arrow_forwardIf G is a cyclic group, prove that the equation x2=e has at most two distinct solutions in G.arrow_forward
- Prove that Ca=Ca1, where Ca is the centralizer of a in the group G.arrow_forward38. Let be the set of all matrices in that have the form with all three numbers , , and nonzero. Prove or disprove that is a group with respect to multiplication.arrow_forwardExercises 35. Prove that any two groups of order are isomorphic.arrow_forward
- Label each of the following statements as either true or false. Two groups can be isomorphic even though their group operations are different.arrow_forwardProve part c of Theorem 3.4. Theorem 3.4: Properties of Group Elements Let G be a group with respect to a binary operation that is written as multiplication. The identity element e in G is unique. For each xG, the inverse x1 in G is unique. For each xG,(x1)1=x. Reverse order law: For any x and y in G, (xy)1=y1x1. Cancellation laws: If a,x, and y are in G, then either of the equations ax=ay or xa=ya implies that x=y.arrow_forward9. Find all homomorphic images of the octic group.arrow_forward
- 39. Let be the set of all matrices in that have the form for arbitrary real numbers , , and . Prove or disprove that is a group with respect to multiplication.arrow_forwardLabel each of the following statements as either true or false. The Generalized Associative Law applies to any group, no matter what the group operation is.arrow_forward24. Prove or disprove that every group of order is abelian.arrow_forward
