Answer this question ​

Answer 1

Step-by-step explanation:

X={1,2,3}

Y={4,5}

X×Y={(1,4),(1,5),(2,4),(2,5),(3,4),(3,5)}

Y×X={(4,1),(4,2),(4,3),(5,1),(5,2),(5,3)}

so X×Y≠Y×X

M={a,b,c}

N={c,d}

M×N={(a,c),(a,d),(b,c),(b,d),(c,c),(c,d)}

N×M={(c,a),(c,b),(c,c),(d,a),(d,b),(d,c)}

so M×N≠N×M

hence proved
