Media aritmetica = (d+b)/2 = (2-√3 + 2+√3)/2=4:2=2
media geometrica = 
 \sqrt{(2+  \sqrt{3} )*(2- \sqrt{3} )}
aplic formula (a-b)*(a+b)= a^{2} - b^{2}
Rezulta media geometrica =  \sqrt{ 2^{2}  -   \sqrt{3} ^{2}  } =  \sqrt{4-3} =1

M aritmetica=a+b÷2= 2+√3+2-√3÷2=4÷2=2
M geometrica= √a×√b= √2+√3×√2-√3=√4-3=√1=1
