Resposta:
-44
Explicação passo-a-passo:
(+2)³- (-6)²
-8 - (+36)
-8 - 36
✅ Após resolver os cálculos, conluímos que o valor da referida expressção numérica é:
[tex]\Large\displaystyle\text{$\begin{gathered}\boxed{\boxed{\:\:\:\bf E = -28\:\:\:}}\end{gathered}$}[/tex]
Resolvendo a expressão numérica:
[tex]\Large\displaystyle\text{$\begin{gathered}\tt E = (+2)^{3} - (-6)^{2}\end{gathered}$}[/tex]
[tex]\Large\displaystyle\text{$\begin{gathered}\tt = 2\cdot2\cdot2 - \left[(-6)\cdot(-6)\right]\end{gathered}$}[/tex]
[tex]\Large\displaystyle\text{$\begin{gathered}\tt = 8 - \left[36\right]\end{gathered}$}[/tex]
[tex]\Large\displaystyle\text{$\begin{gathered}\tt = 8- 36\end{gathered}$}[/tex]
[tex]\Large\displaystyle\text{$\begin{gathered}\tt = -28\end{gathered}$}[/tex]
✅ Portanto, o valor da expressão é:
[tex]\Large\displaystyle\text{$\begin{gathered}\tt E = -28\end{gathered}$}[/tex]
