Question

Aflati nr X stiind ca urmat fractii sunt nr nat​

Answer 1

Răspuns:

a) 6/1 = 6     6/2=3    6/3= 2   6/6=1

x= 1, 2, 3,6

b) 10/(2*1+1) = 10/3 nu da nr natural

10/(2*2+1)= 10/5=2      10/(2*0+1)= 10/1= 10

x= 0 si 2

c) x=0    0+5: (0+1)= 5/1= 5  solutie

x=1    1+5/1+1= 6/2= 3   solutie

x=2   2+5/2+1= 7/3  nu

x=3   3+5/3+1= 8/4=2   solutie

x=4    4+5/4+1= 9/5   nu

x=5    5+5/5+1=10/6 nu

x=0, 1, 3
