Answer 1

Salut!

Calculeaza grupând convenabil termenii :

____________________

⓵ 2 × 4 × 4 =

8 × 4 = 32

⓶ 2 × 4 × 4 =

2 × 16 = 32

____________________

⓵ 9 × 2 × 3 =

18 × 3 = 54

⓶ 9 × 2 × 3 =

9 × 6 = 54

____________________

⓵ 6 × 4 × 2 =

24 × 2 = 48

⓶ 6 × 4 × 2 =

6 × 8 = 48

____________________

⓵ 3 × 2 × 7 =

6 × 7 = 42

⓶ 3 × 2 × 7 =

3 × 14 = 42

____________________

⓵ 5 × 3 × 2 =

15 × 2 = 30

⓶ 5 × 3 × 2 =

5 × 6 = 30

____________________

⓵ 6 × 3 × 3 =

18 × 3 = 54

⓶ 6 × 3 × 3 =

6 × 9 = 54

Succes! :)
