[tex]m + n =\:?[/tex]
[tex]m =1 + \sqrt{0.09} = 1 + 0.3 =1,3[/tex]
[tex]n = 2\sqrt{\frac{49}{25} }= 2 \cdot \sqrt{\frac{7^2}{5^2} } = 2 \frac{7}{5} = \frac{2 \cdot 7}{5} = \frac{14}{5}[/tex]
[tex]m + n = 1,3 + \frac{14}{5} = \frac{13}{10} +\frac{^{2)}14}{5} = \frac{13}{10} +\frac{28}{10} = \frac{13+28}{10} = \frac{41}{10} = 4,1[/tex]
[tex]R: \: m + n = 4.1[/tex]
Sper ca te-am ajutat!
