Exercitiul 4!!!!Va rog!Dau coroana!!!!

Answer 1

a) x:6=13 rest 0

x=13x6

x=78

79:6=13 r.1

80:6=13 r.2

81:6=13 r.3

82:6=13 r.4

83:6=13 r.5

x=78, 79, 80, 81, 82, 83

b)x:8=5

x=8x5

x=40

41:8=5 r.1

47:8=5 r.7

x=40, 41, ..., 47

c)10:7=1 rest 3

11:7=1, rest 4

13:7=1 rest 6

15:7=2 rest 1

20:7=2 rest 6

22:7=3 rest 1

27:7=3 rest 6

29:7=4 rest 1

34:7=5 rest 1

41:7=5rest 6

57:7=8 rest 1

62:7=8 rest6

64:7= 9 rest 1

69:7=9 rest6

71:7=10 rest 1

76:7=10 rest 6

78:7=11 rest1

83:7=11 rest 6

85:7=12 rest 1

90:7=12 rest6

92:7=13 rest 1

97:7=13 rest 6

Suma este: 3+4+5+12x(1+2+3+4+5+6)=

11+12x21=

11+252=

=263

Succes!
