a= 2,(6)+√0,69(4) +1,5
[tex]a = \frac{24}{9} + \frac{25}{30} + \frac{15}{10} [/tex]
Amplificam
[tex] \frac{240}{90} + \frac{75}{90} + \frac{135}{90} [/tex]
a=5
b= 30•[0,1(6)+0,(3)]
[tex]b = 30 \times (\frac{15}{90} + \frac{3}{9}) [/tex]
[tex]30 \times ( \frac{15}{90} + \frac{30}{90} )[/tex]
[tex]30 \times \frac{45}{90} [/tex]
[tex] \frac{30}{1} \times \frac{45}{90} \\ = \frac{1350}{90} \\ = 15[/tex]
b=15
a=5 b=15
Media aritmetica:
