Question

Quando é (-2)+(-5):(-3)

Answer 1

$\Large\mathsf\displaystyle{}\left( - 2\right) + \left( - 5\right) \div \left( - 3\right) \\ \Large\mathsf\displaystyle{} - 2 +\left( - 5\right) \div \left( - 3\right) \\ \Large\mathsf\displaystyle{} - 2 + 5 \div 3 \\ \\ \Large\mathsf\displaystyle{} - 2 + \dfrac{5}{3} \\ \\ \Large\mathsf\displaystyle{} \dfrac{ - 6 + 5}{3} \\\\ \Large\mathsf\displaystyle{} \dfrac{ - 1}{3} \\ \\ \LARGE\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{ - \dfrac{1}{3} }}}\end{gathered} }$

$\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{{ \red{Bons}} \blue{\:Estudos}}}}\end{gathered} }$

Answer 2

Resposta:

$- 0.3. - {3}^{ - 1}$

Explicação passo-a-passo:

$( - 2) + ( - 5) \div ( - 3)$

$- 2 + \frac{5} {3}$

$- \frac{1}{3}$

$- 0.3. - {3}^{ - 1}$
