Question

va rog... e pentru maine!! dau coroana si 15 puncte

Answer 1

D₂₄={1,2,3,4,6,8,12,24}
D₃₆={1,2,3,4,6,9,12,18,36}
D₂₄∩D₃₆={1,2,3,4,6,12}

M₁₂=(12,24,36,48,60.......}
M₆ ={6,12,18,24,30,36,42,48......}
M₁₂∩M₆={M₁₂}

D₁₅={1,3,5,15}
D₈ ={1,2,4,8}
D₁₅∪D₈={1,2,3,4,5,8,15}

D₈={1,2,4,8}
D₈x25={25,50,100,200}

(2n+1)|12
2n+1= 1⇒n=0
2n+1= 3⇒n=1
2n+1= 4⇒n=3/2
2n+1= 6⇒n=5/2
2n+1=12⇒n=11/2
daca nu ai invatat decat multimea N n∈{0,1}
