Answer 1

1)

A = {0, 2, 4, 6, 8} = {x e N | 2 divide x si x ≤ 8}

B = {1, 2, 4, 8, 16, 32} =  {x e N | x = $2^{y}$ si x ≤ 32}

C = {0, 3, 6, 9, 12, ...} = {x e N | 3 divide x}

2)

A = {2, 3, ..., 6}

B = {0, 1}

C = {-3, -2, -1, 0, 1}

D = {4, 5, 6, 7}

E = {-6, -5, -4, 4, 5, 6}

F = {-6, -5, -4, -3, 3, 4, 5, 6}

3)

M = {-7, -1/3, -$\sqrt{4}$, 0, -$\sqrt{2}$, $\sqrt{3}$, 0,5, 7}

A = {0, 7}

B = {-7, -$\sqrt{4}$, 0, 7}

C = {-7, -$\sqrt{4}$, -1/3, 0, 0,5, 7}

D = M

4) A = {2, 3, 4}

B = {1, 2, 3, 6}

C = {1/6, 1/2, 2/3, 1, 3/2, 4/3, 2, 3, 4}
