Example 4:

Example 4 If P={1,2}, form the set P x P x P. 
Solution : we have, P x P x P=[(1,1,1), (1,1,2), (1,2,1), (1,2,2), (2,1,1), (2,1,2), (2,2,1), (2,2,2)}.

Dear Student

The Pic posted by you already contains the answer to the solution; which is found using the Cartesian-product of sets taken in pair
EXAMPLE : for PxPxP first find PxP and then find Px(PxP)

Below is one more illustration for making you understand the concept of Cartesian Product and you can refer to the study material provided on the website for more information.
