Răspuns:

Explicație pas cu pas:

a)

E = {0, 1, 2}

F = {-1, 1}

E x F = {(0, -1), (0, 1), (1, -1), (1, 1), (2, -1), (2, 1)}

F x E = {(-1, 0), (-1, 1), (-1, 2), (1, 0), (1, 1), (1, 2)}

b)

E = {-2, -1, 0, 1, 2}

F = {1, 2}

E x F = {(-2, 1), (-2, 2), (-1, 1), (-1, 2), (0, 1), (0, 2), (1, 1), (1, 2), (2, 1), (2, 2)}

F x E = {(1, -2), (1, -1), (1, 0), (1, 1), (1, 2), (2, -2), (2, -1), (2, 0), (2, 1), (2, 2)}
