True or False Label each of the following statements as either true or false. 6. Every permutation can be expressed as a product of disjoint cycles.
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.

Which of the following is NOT closed in an operation *? a. N= {1,2,3,...} under usual addition b. N {1,2,3,...} under usual subtraction c. Z {...-3, -2, -1, 0, 1, 2, 3, ...} under usual multiplication d. Z* under usual multiplication
3. We say that an integer c is a common divisor of integers a and b if cla and c|b. We say c is the greatest common divisor if c is the largest common divisor of a and b, and in this case we denoted c by gcd(a, b). For example, the common divisors of a = = 30 and b = 18 are 1, 2, 3, and 6. As 6 is the largest of these divisors, gcd(30, 18) = 6. (a) Compute the greatest common divisor of 63 and 255. (We'll later see an efficient way to do this, but for now try to do this "by hand.") (b) Show if c is a common divisor of a and b, then c is also a common divisor of ax and bx for every integer x.
There are lots of ways to split the integers into two sets whose intersection is empty. An example is to let A = {odd integers} and B = {even integers}. Note that the union of these sets is all the integers but no individual number is in both sets (i.e. union is everything and intersection is empty). Define another way to accomplish this that is different than the example provided. Note that you can use a different group other than integers if you like.
Which of the following is NOT a binary operation? a. GeZ is defined as a b. GENis defined as a c. GeZ is defined as a *b=a-b d. GeQ is defined as a *b ab/2 b = a - b. *b = 2a + 3b
