78:6=13 79:6=13rest1 80:6=13rest2 81:6=13rest3 82:6=13rest4 83:6=13rest5 84:6=13rest6 85:6=13rest7 86:6=13rest8 87:6=13rest9 88:6=13rest10 89:6=13rest11 90:6=13rest12 Răspuns: 78,79,80,81,82,83,84,85,86,87,88,89,90

Answer 2

a:6=c13,r(0,1,2......12). D=ÎxC+r. R<Î. Adică: a=6x13+r. rest 0. :6x13+0=78. Rest 1: 6x13+1=79 Rest 2: 6x13+2=80..... Si continui tot asa pana la: rest=12: 6x13+12=90
