C......
Vă rog să mă ajutați-mă pana la g, dau coroană

Answer 1

a) 45+7+[307-816:(9-5)]-8×18=
52+[307-816:4]-8×16=
52+[307-204]-144=
52+103-144=
155-144=11
b)406-4×[3×(30-18:6:3)]=
406-4×[3×(30-1)]=
406-4×[3×29]=
406-4×87=
406-348=58
c)832:8+[40+8×(100:5-72:4)]×10=
104+[40+8×(20-18)]×10=
104+[40+8×2]×10=
104+[40+16]×10=
104+56×10=
104+560=664
d)25+6×[107-100:(8-3)]-9×19=
25+6×[107-100:5]-171=
26+6×[107-20]-171=
26+6×87-171=
26+522-171=
548-171=377
e)1+3×[3+8×(7-3)+3×(5+6)]=
1+3×[3+32+33]=
1+3×68=204+1=205
g)5+[7+3×(7-2)]:2-6=
5+[7+3×5]:2-6=
5+[7+15]:2-6=
5+22:2-6=16-6=10
