Question

Scrie fiecare adunare de termeni egali ca inmultire:2+2+2:::2+2+2+2:::3+3+3+3:::3+3+3+3+3:::5+5+5:::5+5+5+5:::10+10+10:::10+10+10+10

Answer 1

2+2+2 = 3 x 2 = 6
2+2+2+2= 4 x 2 = 8
3+3+3+3= 4 x 3 = 12
3+3+3+3+3 = 5 x 3 = 15
5+5+5 = 3 x 5 = 15
5+5+5+5 = 4 x 5 = 20
10+10+10= 3 x 10 = 30
10+10+10+10 = 4 x 10 = 40→ de 4 ori cate 10
