Question

5.Verifică egalitățile:
2×[624÷4-(56÷2+39)] =132÷2+(674-522÷2)×0
5×[3×(14+15×3)-(5×118)÷5]=(824÷4+9)×3-451

Answer 1

2×[624÷4-(56÷2+39)] =132÷2+(674-522÷2)×0
2×[156-(28+39)] =66+0
2×156-67=66
312-67=66
245=66 fals



5×[3×(14+15×3)-(5×118)÷5]=(824÷4+9)×3-451
5×[3×(14+45)-590÷5]=(206+9)×3-451
5×(3×59-590÷5)=215×3-451
5×(177-118)=645-451
5×59=194
295=194

Answer 2

2 x ( 624 : 4 ) - ( 56 : 2 + 39 ) = 132:2 + (674 - 522 : 2) x 0 =
2 x 156 - ( 28 +39 ) = 66+ ( 674- 261 ) x0 =
312 - 67 = 66 + 413 x 0 =
245 = 66 + 0
245 = 66
