Question

If A=(3,4,5) B=(8,9) then find AXB BXA

Answer 1

Answer:

Given ,

• A = {3,4,5}
• B = {8,9}

To find :—

1. A × B
2. B × A

Now,

(1) A × B = { 3 , 4 , 5 } × { 8, 9 }

= { (3,8) , (3,9) , (4,8) , (4,9) , (5,8) ,(5,9)}

(2) B × A = { 8, 9 } × { 3 , 4 , 5 }

= {(8,3),(8,4),(8,5),(9,3),(9,4),(9,5)}
