PLS IMI TREBUIE IN CSTEVA MINUTE

Answer 1

Răspuns:

n={0,1,2,3,5,11}

Explicație pas cu pas:

12/n+ 1 trebuie sa fie numar natural

D12 ={1,2,3,4,6,12 }

n+1=1 => n=0

n+1=2 => n=1

n+1=3 => n=2

n+1=4 =>n=3

n+1=6 =>n=5

n+1=12 =>n=11

n={0,1,2,3,5,11}

Verificare :

12/1=12

12/2=6

12/3=4

12/4=3

12/6=2

12/12=1
