Question

Verifica daca au loc egalitatile :
4x3+ (7 – 4) = 4 x (3 + 7) - 4
12:6 + 8 - 3 = (12: 6) + (8 - 3)​

Answer 1

4x3+ (7 – 4) = 4 x (3 + 7) - 4

12+3= 4×10-4

15= 40- 4

15≠ 36 (nu are loc egalitatea)

12:6 + 8 - 3 = (12: 6) + (8 - 3)

2+8-3= 2+5

10-3= 7

7= 7 (are loc egalitatea)

Answer 2

4x3+(7-4)=4x(3+7)-4
12+3=4x10-4
15=40-4
15=36 (nu)

12:6+8-3=(12:6)+(8-3)
2+5=2+5
7=7 (da)
