Question

vaaaaa rooggggg multtt

Answer 1

b)
n=12m+5
n=15k+8
adun la prima si la a doua 7

n+7=12(m+1)
n+7=15(k+1)
de aici rezulta ca n+7 este c.m.m.m.c (12;15)
n+7=60
n=53

c)
 la fel ca b)
n=24m+10
n=36k+22
adun la fiecare 14
n+14=24(m+1)
n+14=36(k+1)
n+14=c.m.m.m.c (24;36) =72
n=72-14=58

16)
a)
127=na+7
53=nb+5
76=nc+4, a,b,c ∈N*

120=na
48=nb
72=nc
n=c.m.m.d.c (120;48;72) = 24
n=24

b)
47=na+2
53=nb+3
64=nc+4

45=na
50=nb
60=nc
n=c.m.m.d.c (45;50;60)=5
n=5

vezi si tu ce raspunsuri ai in carte si sa-mi scri daca ai nelamuriri
