Question

Va implooorrrrrrrrrrrrrrrrrrrrrrrrrrrr

Answer 1

Răspuns:

Explicație pas cu pas:

a)

D3 = {1, 3} multime finita, 2 elemente

D4 = {1, 2, 4} multime finita, 3 elemente

D5 = {1, 5} multime finita, 2 elemente

D13 = {1, 13} multime finita, 2 elemente

D18 = {1, 2, 3, 6, 9, 18} multime finita, 6 elemente

D100 = {1, 2, 4, 5, 10, 20, 25, 50, 100} multime finita, 9 elemente

b)

toate multimile sunt infinite

M3 = {0, 3, 6, 9, 12, ...+∞}

M4 = {0, 4, 8, 12, 16, ...+∞}

M5 = {0, 5, 10, 15, 20, ...+∞}

M13 = {0, 13, 26, 39, 52, ...+∞}

M18 = {0, 18, 36, 54, 72, ...+∞}

M3 = {0, 100, 200, 300, 400, ...+∞}

c)

{0, 2, 4, 6, 8} multime finita, 5 elemente

d)

{1, 3, 5, 7,, 9} multime finita, 9 elemente

e)

{0, 2, 4, 6, 8, 10, 12, ...., +∞} multime infinita
