Question

Alguém me ajuda? não consegui resolver a expressão:

Answer 1

$(-\dfrac{7}{16}) + 5^3 - (\dfrac{2}{3} + \dfrac{7}{3})^3 - (\dfrac{\sqrt{25}}{9})^{-2} \\ \\ \\ (-\dfrac{7}{16}) + 125 - (3)^3 - (\dfrac{5}{9})^{-2} \\ \\ \\ (-\dfrac{7}{16}) + 125 - 27 - (\dfrac{9}{5})^2 \\ \\ \\ (-\dfrac{7}{16}) + 98 - (\dfrac{81}{25}) \\ \\ \\ (-\dfrac{7}{16}) + (\dfrac{2369}{25}) \\ \\ \\ =\ \textgreater \ (\dfrac{37729}{400})$

Answer 2

$(\frac{-7}{16}) + 5^{3} - ( \frac{2}{3} + \frac{7}{3}) ^{3} - ( \frac{ \sqrt{25} }{9}) -^{2}$



$(\frac{-7}{16}) +125 - ( \frac{9}{3} ) ^{3} -( \frac{5}{9} ) -^{2}$



$( \frac{-7}{16} ) + 125 -( \frac{729}{27}) - (\frac{81}{25} )$



$( \frac{-7}{16} ) + 125 - 27 - (\frac{81}{25} )$


$( \frac{-7}{16}) +98 - (\frac{81}{25} )$



$( \frac{-7}{16}) + ( \frac{2369}{25} )$



$(\frac{-175+37904}{400} )$




$\frac{37729}{400} = 94,3225$
