a)Verificati egalitatile urmatoare:
(6,15) × [6,15]=6×15;
(18,24)×[18,24]=18,24;
(8,20)×[8,20]=8,20;
(28,42)×[28,42]=28,42.
b)Daca (a,b)=6 si [a,b]=72, aflati a × b,
c)Daca (a,b)=12 si a × b =864, aflati [a,b].
d)Daca [a,b]=96 si a × b=3072,aflati (a,b).
Daca [a,b] =432, (a,b)=12 si a =48,aflati b.
Va rog frumos!

A) A, F, F, F
B) a*b= (a,b)*[a,b]=6*72=432
C) [a,b] = (a*b) / (a,b) = 864/12= 72
D) (a,b) = (a*b) / [a,b] = 3072/96 = 32
a*b = [a,b] * (a,b) = 432*12 = 5184
48*b = 5184 => b=5184/48
b=108
