- Assume that is a binary operation on a non empty set A, and suppose that is both commutative and associative. Use the definitions of the commutative and associative properties to show that [ (ab)c ]d=(dc)(ab) for all a,b,c and d in 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_forwardTrue or False Label each of the following statements as either true or false. 2. If * is a binary operation on a nonempty set , then is closed with respect to *.arrow_forward
- Label each of the following statements as either true or false. 1. , for every nonempty set A.arrow_forwardTrue or False Label each of the following statements as either true or false. 1. If a binary operation on a nonempty set is commutative, then an identity element will exist in .arrow_forward2. Prove that is commutative if and only if is commutative.arrow_forward
