a)
$\frac{3}{5}$
si
$\frac{7}{5}$
b)
$6 \sqrt{6}$
si
$8 \sqrt{6}$
​

Answer 1

Răspuns:

Explicație pas cu pas:

a)

$m_{a} = \dfrac{\dfrac{3}{5}+\dfrac{7}{5}}{2} = \dfrac{\dfrac{3+7}{5}}{2} = \dfrac{10}{2*5} = \dfrac{10}{10} = 1$

b)

$m_{a} = \dfrac{6\sqrt{6}+8\sqrt{6}}{2} = \dfrac{14\sqrt{6}}{2} = 7\sqrt{6}$
