Ajutor, vă rog frumos!​

Answer 1

Răspuns:

ab=1920

cmmdc (a,b)=8

a=8x

b=8y

ab=8x·8y=64xy=1920

xy=1920:64=>xy=30

x=1 , y=30=>a=8 , b=240

x=30 , y=1=>a=240 , b=8

x=5 , y=6=>a=40 , b=48

x=6 , y=5=>a=48 , b=40

x=2 , y=15=>a=16 , b=120

x=15 , y=2=>a=120 , b=16

x=3 , y=10=>a=24 , b=80

x=10 , y=3=>a=80 , b=24

valoarea minima a sumei a+b=40+48=88

valoarea minima a diferentei b-a=48-40=8
