  ${\left(-2\right)}^3=-8$

Explanation of Solution

Given information:

  ${\left(-2\right)}^3$

Calculation:

  ${\left(-2\right)}^3$

  $\begin{array}{l}{\left(-2\right)}^3=\left(-2\right)\times \left(-2\right)\times \left(-2\right)\\ \Rightarrow {\left(-2\right)}^3=4\times \left(-2\right)\\ \Rightarrow {\left(-2\right)}^3=-8\end{array}$
