a= 2,(6)+√0,69(4) +1,5

$a = \frac{24}{9} + \frac{25}{30} + \frac{15}{10}$

Amplificam

$\frac{240}{90} + \frac{75}{90} + \frac{135}{90}$

a=5

b= 30•[0,1(6)+0,(3)]

$b = 30 \times (\frac{15}{90} + \frac{3}{9})$

$30 \times ( \frac{15}{90} + \frac{30}{90} )$

$30 \times \frac{45}{90}$

$\frac{30}{1} \times \frac{45}{90} \\ = \frac{1350}{90} \\ = 15$

b=15

a=5 b=15

Media aritmetica:

(a+b):2

(5+15):2

30:2

15

$m_{a} = 15$

Media geometrică:

√a•b

√5•15

√75

8,6(6)

$m_{g} = 8.6(6)$

Sper că te-am ajutat. Spor la teme
