a) (-1,4)³​

Answer 1

$\large\sf{}\left( - 1,4\right)^{3} \\ \\ \large\sf{} \dfrac{14}{10} \\ \\ \large\sf{} \dfrac{14 \div 2}{10 \div 2} \\ \\ \large\sf{} \dfrac{7}{5} \\ \\ \large\sf{}\left( - \dfrac{7}{5} \right)^{3} \\ \\ \large\sf{} - \left( \dfrac{7}{5} \right)^{3} \\ \\ \large\sf{} - \frac{ {7}^{3} }{ {5}^{3} } \\ \\ {\large\boxed{\boxed{  { \large \sf - \dfrac{343}{125} }}}}$

${\large\boxed{\boxed{  { \large \sf Bons~Estudos }}}}$
