Question

cum se rezolva va rog ​

Answer 1

Explicație pas cu pas:

1) a) (a+b)/2=2, a+b= 4

mg=√(ab),

a, b€ N, 0<a<b

4=0+4=1+3=2+2=3+1=4+0

a= 1, b = 3, mg=√1*3=√3

b) mg=√(ab)= 3,

a, b€ N, 0<a<b

3=1*3, a=1, b= 3, ma =(a+b)/2= 4/2=2

mp= (a*2b+b*2a)/(a+b)= (4ab)/(a+b)= (4*9)/4= 9

2) x-2√3= 0, x=2√3

6√3-y= 0, y= 6√3

2/(x+y)=2/(2√3+6√3)= 2/(8√3)= 1/(4√3)= √3/12

1/(√(xy))= 1/√(12*3= 1/6

2/(x+y)>1/(√(xy))
