Question

Rezolvati ex: 12x[25:(35x25-34x25)+256:4]-60 urmatorul {(240:8+670):2x8-700}:3+3= urmatorul 123x2-{14x4-(36:6+10)}:5 urmatorul 400+480:4-{68:2+4x(20+12+18)]

Answer 1

12x[25:(35x25-34x25)+256:4)-60=
12x[25:(875-850)+64)- 60=
12x(25:25+64)-60=
12x(1+64)-60
12x65-60=
780-60=720


[(240:8+670):2x8-700]:3+3=
[(30+670): 2x8-700]:3+3=
(700:2x8-700):3+3=
(350x8-700):3+3=
(2800-700):3+3=
2100:3+3=
700+3= 703


123x2-[14x4-(36:6+10)]:5=
245-[56-(6+10)]:5=
245- (56-16) :5=
245- 40:5=
245-8= 237

400+480:4-[68:2+4x(20+12+18)]=
400+120-[34+4x(32+18)]=
400+120-(34+4x50)=
400+120-(34+200)=
400+120-234=
520-234= 286

   Baftă, nu știu dacă am scris chiar tot corect, dar măcar am încercat. :)
