Question

Buna imi puteti rezolva acum urgent ceva:: n+8pe 30 sa fie numar zecimal periodic simplu si numar zecimal periodic mixt??

Answer 1

(n+8)/30=10/30=1/3=0,(3)

n+8=10 n=2

(n+8)/30=25/30=5/6=0,8(3)

n+8=25... n=17

asta daca se cerea n natural

pt n intreg era mai simplu

(n+8)/30=5/30 =1/6=0,1(6)

n+8=5...n=-3
