Answer:

[tex]A\times B=\{(2,2),(2,6),(2,8),(5,2),(5,6),(5,8)\}[/tex]

Step-by-step explanation:

Remember, the Cartesian product of two sets A and B is the set:

[tex]A\times B=\{(a,b): a\in A, b\in B\}[/tex]

Now, if [tex]A=\{2,5\}[/tex] and [tex]B=\{2,6,8\}[/tex]

[tex]A\times B=\{(2,2),(2,6),(2,8),(5,2),(5,6),(5,8)\}[/tex]
