​

Answer 1

Answer:

Q:2- If P=(a,b,c) and Q=(r) , from the set P×Q ?

answer:- P={a,b,c} and Q= (r)

P×Q={a,b,c} ×{r}

P×Q={(a,r),(b,r),(c,r)}

Q×P={r} ×{a,b,c}

Q×P={(r,a),(r,b),(r,c)}

since(a,r) not equal (r,a)

P×Q not equal Q×P

since the corresponding first and second elements are not equal, hence the two ordered pairs are not equal.
