Question

alguien lo sabe? me ayudan por fa​

Answer 1

Respuesta:

a) 514/25

b) -69/7

Explicación paso a paso:

a)

$(10^{8}:10^{6})*\frac{1}{5}+(\frac{3}{5}-\frac{1}{5})^{2}+\frac{2}{7}*\frac{7}{5}$$10^{2}*\frac{1}{5}+(\frac{2}{5})^{2}+\frac{14}{35}$

$100*\frac{1}{5}+\frac{4}{25}+\frac{2}{5}$

$20+\frac{4+10}{25}$

20 + 14/25

514/25

b)

$(\frac{1}{2}+\frac{1}{5})^{-1}:\frac{5}{4}+\sqrt{2-\frac{7}{16}}-(\frac{2}{7})^{-2}$

$(\frac{5+2}{10})^{-1}:\frac{5}{4}+\sqrt{\frac{32-7}{16}}-(\frac{7}{2})^{2}$

$(\frac{7}{10})^{-1}:\frac{5}{4}+\sqrt{\frac{25}{16}}-\frac{49}{4}$

$\frac{10}{7}:\frac{5}{4}+\frac{5}{4}-\frac{49}{4}$

$\frac{40}{35}-11$

$\frac{8}{7}-11$

$\frac{8-77}{11}$

-69/7
