Question

Va rog, 35 e urgent! Multumesc mult!!

Answer 1

M={-4, -3, -2, -1, 1, 2, 3, 4}
n=3
cel mai mic: -4
cel mai mare: +4

Answer 2

a) daca n=0 M=Ф  (modulul trebuie sa fie pozitiv)
daca n=1 M={0}-{0}=Ф
daca n=2 M={-2,-1,0,1,2}-{0}={-2,-1,1,2}
daca n=3 M={-4,-3,-2,-1,0,1,2,3,4}-{0}={-4,-3,-2,-1,1,2,3,4} are 8 elemente
daca n≥4 card M>8  (card M= numarul elem lui M)
deci n=3
b) pentru n fixat M=(-2n+1,2n-1)∩Zˣ={-2n+2,...2n-2} n≥2
 min M=-2n+2, max M=2n-2

O zi buna!
