Question

Verifică egalitățile:
0+[(1×2+3×4)÷(56÷7÷8)+9]×10=(9+8+7+6)÷5-(4×3÷2-1);
45={3005-[913×(600-24×25)+9320]÷4}÷15.

Answer 1

0+[(1×2+3×4):(56:7:8)+9]×10=(9+8+7+6):5-(4×3:2-1).... 0+[(2+12):(8:8)+9]×10=30:5-(12:2-1)...0+(14:1+9)×10=6-(6-1)....0+23×10=6-5....0+230=1...230=1 fals....... .... 45={3005-[913×(600-24×25)+9320]:4}:15.....45={3005-[913×(600-600)+9320]:4}:15.... 45=[3005-(913×0+9320):4]:15.... 45=[3005-(0+9320):4]:15..... 45=(3005-9320:4):15... 45=(3005-2330):15... 45=675:15.... 45=45 adevarat
