Question

Calculati media aritmetica a numerelor a= 2- radical 3 si b= 2+ radical 3

Answer 1

a=2-√3 
b=2+√3
ma=(2-√3+2+√3)/2=4/2=2
mg=√(2-√3)(2+√3)=√(4-3)=1

 a=9+4√2
 b=9-4√2
ma=(9+4√2+9-4√2)/2=18/2=9
mg=√(9+4√2)(9-4√2)=√(81-32)=√49=7

a=(√3-√2)² =3-2√6+2=5-2√6
b=(√3+√2)² =3+2√6+2=5+2√6
ma=(5-2√6+5+2√6)/2=10/2=5
mg=√(5-2√6)(5+2√6)=√(25-24)=1
