Buna va rog frumos dacă vreti puteți să mă ajutați și pe mine la trei execiti dau coroana
a.(3×3+3:3+3×3:3):13+(33:3+3-33:11+11):22=
b.1+{2+[3+(4×18-3×18)-2]-1}+10=
c)10667:{[(21024:4+255:17)×2+1119]-2004}+4×4:4=

Answer 1

a)
(3×3+3:3+3×3:3):13+(33:3+3-33:11+11):22=
(9+1+9:3):13+(11+3-3+11):22=
(10+3):13+(14-3+11):22=
13:13+(11+11):22=
1+22:22=
1+1=
2


b)
1+{2+[3+(4×18-3×18)-2]-1}+10=
1+{2+[3+(72-54)-2]-1}+10=
1+[2+(3+18-2)-1]+10=
1+[2+(21-2)-1]+10=
1+(2+19-1)+10=
1+(21-1)+10=
1+20+10=
21+10=
31


c)
10667:{[(21024:4+255:17)×2+1119]-2004}+4×4:4=

10667:{[(5256+15)×2+1119]-2004}+16:4=

10667:[(5271×2+1119)-2004]+4=

10667:[(10542+1119)-2004]+4=

10667:(11661-2004)+4=

10667:9657+4=

1,10 (aprox) +4=

5,10 (aprox)
