Media geometrica a nr 1,25 si 1,(6)​

Răspuns :

[tex]Mg=\sqrt{1,25*1,(6)}=\sqrt{\frac{125}{100}*\frac{15}{9} }=\sqrt{\frac{5*25*3*5}{900}}=\sqrt{\frac{25*25*3}{30*30}}=\frac{25}{30}\sqrt{3}=\frac{5}{6}\sqrt{3}[/tex]

Mg = √a×b

Mg = √1,25×1,(6)

= √125/100×(16-1)/9

= √5/4×15/9

= √75/36

= √3×5²/6²

= 5√3/6
