if A= (2 3 8) B =(2 7 5) find a×b​

Answer:

{(2,2) , (2,7) , (2,5) , (3,2) , (3,7) , (3,5) , (8,2) , (8,7) , (8,5)}

Step-by-step explanation:

Given :

 Set A =  (2 3 8)

 Set B =  (2 7 5)

Unknown:

Product of two sets a x b;

Solution:

Set A =  (2 3 8)

 Set B =  (2 7 5)

   The cartesian product  of two sets is expressed as the order pairs of elements from A to B;

A =  (2 3 8)

B =  (2 7 5)

A x B = {(2,2) , (2,7) , (2,5) , (3,2) , (3,7) , (3,5) , (8,2) , (8,7) , (8,5)}
