2 . a 3+5=8 , 8×4=32

b 2+3+4=10, 10 ×8=80

Sper să te ajute

Answer 2

1) metoda 1 (dam factor comun):5×(4+3)=5×4+5×3=35

6×(5+4)=6×5+6×4=54

5×6+5×3=5×(6+3)=45

3×6+6×7=6×(3+7)=60

metoda 2 (le calculam normal):5×(4+3)=35

6×(5+4)=54

5×6+5×3=45

3×6+6×7=60

2) a) 4×(5+3)=32

b) 8×(2+3+4)=72

3) mod 1: 4×(3+3)=24

mod 2:4×3+4×3=24
