Question

Calculați suma numerelor naturale care împărțite la opt dau câtul 13. VA ROOOOOGGG​

Answer 1

Răspuns:

R < I=>R < 8=>R∈{0,1,2,3,4,5,6,7}

13·8+0= 104

13·8+1= 105

13·8+2= 106

13·8+3= 107

13·8+4= 108

13·8+5= 109

13·8+6=110

13·8+7= 111

S=104+105+106+107+108+109+110+111=860

Answer 2

n : 8 = 13 rest 0

n = 8 × 13 + 0

n = 104 + 0

n = 104

n : 8 = 13 rest 1

n = 8 × 13 + 1

n = 104 + 1

n = 105

n : 8 = 13 rest 2

n = 8 × 13 + 2

n = 104 + 2

n = 106

n : 8 = 13 rest 3

n = 8 × 13 + 3

n = 104 + 3

n = 107

n : 8 = 13 rest 4

n = 8 × 13 + 4

n = 104 + 4

n = 108

n : 8 = 13 rest 5

n =  8 × 13 + 5

n = 104 + 5

n = 109

n : 8 = 13 rest 6

n = 8 × 13 + 6

n = 104 + 6

n = 110

n : 8 = 13 rest 7

n = 8 × 13 + 7

n = 104 + 7

n = 111

104 + 105 + 106 + 107 + 108 + 109 + 110 + 111 = 860
