Question

Determinați mulțimea formată din primii 5 multipli ai numărului:5; 7; 10; 15; 20.

Answer 1

Răspuns:

M₅={0, 5, 10, 15, 20}

5 × 0 = 0

5 × 1 = 5

5 × 2 = 10

5 × 3 = 15

5 × 4 = 20

M₇={0, 7, 14, 21, 28}

7 × 0 = 0

7 × 1 = 7

7 × 2 = 14

7 × 3 = 21

7 × 4 = 28

M₁₀={ 0, 10, 20, 30, 40}

10 × 0 = 0

10 × 1 = 10

10 × 2 = 20

10 × 3 = 30

10 × 4 = 40

M₁₅={0, 15, 30, 45, 60}

15 × 0 = 0

15 × 1 = 15

15 × 2 = 30

15 × 3 = 45

15 × 4 = 60

M₂₀={ 0, 20, 40, 60, 80}

20 × 0 = 0

20 × 1 = 20

20 × 2 = 40

20 × 3 = 60

20 × 4 = 80
