Explain why (A × B) x (C × D) and A × (B × C) × D are not the same.

Solution:Step 1:In this question, we have to explain that (A × B) x (C × D) and A × (B × C) × D are not the same.Step 2:Let us consider A= {p}, B ={q}, C = {r}, D ={s}We can say that (A × B) x (C × D) ={(p,q),(r,s)}.So, (A × B)and (CThen the elements in set are in the form of (A × B) x (C × D) is in the form of ((p,q),(r,s)), here (A × B)and (C.
