Question

Calcule o valor numérico das expressões:

Answer 1

Resposta:

$\frac{1 - \frac{1}{2} }{ \frac{3}{4} } + \frac{ \frac{1}{5} }{(1 - { \frac{4}{5}) }^{2} } = \frac{ \frac{1}{2} }{ \frac{3}{4} } + \frac{ \frac{1}{5} }{( { \frac{1}{5}) }^{2} } \\ \frac{1}{2} \times \frac{4}{3} + \frac{1}{5} \times \frac{25}{1} \\ \frac{4}{6} + \frac{25}{5} = \frac{4}{6} + 5 = \frac{34}{6} \: ou \: \frac{17}{3}$
