Example:A×BC={(1,x,a),(1,x,b),(1,x,C)(1,y,a), (1y,b),(1,y,c),(2,x,a),(2,x,b),(2,x,c),(2,y,a),(2,y,b), (2y,c)} IfA= A for i=1,2,,n, then a1×A,×…× A, by an Example: Let A represent the set of all students at an university, and let B represent the set of all course at the university. What is the cartesian product of A×B? The Cartesian product of A XB consists of all the ordered pairs of the form(a, b), where a is a student at the university and b is a course offered at the university. The set A XB can be used to represent all possible enrollments of students in courses at the universityExample:A×B×C={(1,x,a),(1,x,b),(1,x,c),(1,y,a), (1,y,b), (1,y,c),(2,x,a),(2,x,b),(2,x,c),(2,y,a),(2,y,b), (2,y,c)}。 If Ai=A for i=1,2,…,n, then A1×A2×…×An by An .
