If `A={x:x^(2)-5x+6=0},B={2,4},C={4,5}` then find `Axx(BnnC)`

A

{(2, 4), (3, 4)}

B

{(4, 2), (4, 3)}

C

{(2, 4), (3, 4), (4, 4)}

D

`{(2, 2), (3, 3), (4, 4), (5, 5)}`

Text Solution

Verified by Experts

The correct Answer is:
A
We have,
A={2, 3}, B={2, 4}, and C={4, 5}
`therefore B nn C = {4}`
`impliesA xx (BnnC)={2, 3}xx{4}={(2,4),(3, 4)}`
