- Write out the elements of P(A) for the set A={ a,b,c }, and construct an addition table for P(A) using addition as defined in Exercise 42. (Sec. 1.1,7c) Sec. 1.1,7c 42. For an arbitrary set A, the power set P(A) was defined in Section 1.1 by P(A)={ XXA }, and addition in P(A) was defined by X+Y=(XY)(XY) =(XY)(YX) Prove that P(A) is a group with respect to this operation of addition. If A has n distinct elements, state the order of P(A).arrow_forward43. Let the operation of addition be as defined in Exercise 42. Prove each of the following statements. a. b. 42. Let the operation of addition be defined on subsets and of byarrow_forward[Type here] 7. Let be the set of all ordered pairs of integers and . Equality, addition, and multiplication are defined as follows: if and only if and in , Given that is a ring, determine whether is commutative and whether has a unity. Justify your decisions.
