[tex]m_{a} =\frac{3+22}{2} =\frac{25}{2} = 12,5[/tex]
[tex]m_{g} =\sqrt{3*22} =\sqrt{3} *\sqrt{22}[/tex] ≈ [tex]1,7*4,7=7,99[/tex]

[tex]m_{a} =\frac{0,625+2,5}{2} =\frac{3,125}{2} =1,5625[/tex]
Aproximăm prin lipsă la zecimi: [tex]m_{a} =1,5[/tex]
[tex]m_{g} =\sqrt{0,625*2,5} =\sqrt{1,5625} =\sqrt{\frac{15625}{10000}^{(625} }=\sqrt{\frac{25}{16} } =\frac{\sqrt{25} }{\sqrt{16} } =\frac{5}{4} =1,25[/tex]
Aproximăm prin lipsă la zecimi: [tex]m_{g} =1,2[/tex]
