Va rog ajutati ma cu exercitiul (608 :16 -270:30).2-19.3 [(205:5+13.5):2-2.25]:3+1 25-[300:10+2(725:5-29.5)-4.5] 3.[35+16.(230-19.12)]-[14.3+82.3-4.(2+4.5)] [302+19.(68-8.6)]:2-2.17.10 25.13+325:[178-17.(27.7-18.10)]5

Answer 1

(608÷16-270÷30)×2-19×3=
=(38-9)×2-57=2×38-2×9-57=76-18-57=1
[(205÷5+13×5)÷2-2×25]÷3+1=
=[(41+65)÷2-50]÷3+1=(106÷2-50)÷3+1=(53-50)÷3+1=3÷3+1=2
25-[300÷10+2(725÷5-29×5)-4×5]=
=25-[30+2(145-145)-20]=
=25-(30+2×0-20)=25-10=15
3×[25+16(230-19×12)]-[14×3+82×3-4(2+4×5)]=
3×[25+16(230-228)]-(42+246-4×22)=
=3×(25+16×2)-(42+246-88)=
=3×(25+32)-200=3×67-200=201-200=1
[302+19×(68-8×6)]÷2-2×17×10=
=(302+19×20)÷2-340=
=(302+380)÷2-340=682÷2-340=341-340=1
25×13+325÷[178-17×(27×7-18×10)]×5=
=325+325÷[178-17×(189-180)]×5=
=325+325÷(178-17×9)×5=
=325+325÷(178-153)×5=
=325+325÷25×5=325+13×5=325+65=390
