Question

aflati toate numerele naturale nenule care impartite la 7 dau restul egal cu catul.

Answer 1

8 / 7 = 1 rest 1
16 / 7 = 2 rest 2
24 / 7 = 3 rest 3
32 / 7 = 4 rest 4
40 / 7 = 5 rest 5
48 / 7 = 6 rest 6

Answer 2

x:7 = c rest c
x= 7c + c
x= 8c   <=>x=M₈  =>x={8,16,24,32,40,48}

1) x=8 =>  8:7=1 rest 1

2) x=16  => 16:7=2 rest 2

3) x=24  => 24:7=3 rest 3

4) x=32 => 32:7=4 rest 4

5) x=40 => 40:7= 5 rest 5

6) x=48 => 48:7=6 rest 6
