Let A = The set of all natural numbers less than 8, B = The set of all prime numbers less than 8, C = The set of even prime numbers. Verify that (A \cap B) \times C = (A \times C) \cap (B \times C)
 
Answer:
 
To prove:
 
(A \cap B) \times C = (A \times C) \cap (B \times C)
 
Explanation:
 
A \cap B = i,i,i,i
 
(A \cap B) \times C = \{\}
 
A \times C = \{\}
 
B \times C =\{\}
 
(A \times C) \cap (B \times C) = \{\}\)
 
As a result, (A \cap B) \times C = (A \times C) \cap (B \times C)
 
Hence, we proved.
