Question

Va rog, am nevoie!! ​

Answer 1

Răspuns:

375

Explicație pas cu pas:

a : 6 = 10 => a = 6x10 = 60

60:6 = 10 rest 0

61:6 = 10 rest 1

----------------------

65:6 = 10 rest 5

Suma = 60+61+62+63+64+65 = (60+65)·6:2 = 125·3 = 375

Answer 2

n : 6 = 10 + rest

impartitorul 6 => restul = 0, 1, 2, 3, 4, 5

n = 6×10 + 0, 1, 2, 3, 4, 5

n = 60 + 0, 1, 2, 3, 4, 5

n = 60, 61, 62, 63, 64, 65

S = 60+61+62+63+64+65

S = 60×6 + (1 + 2 + 3 + 4 + 5 )

S = 360 + 15

S = 375
