Question

Calculate the value of the following :

${\left(-\frac{2}{8}\right)}^3$

Answer 1

Given ,

The expression is ${\left(-\frac{2}{8}\right)}^3$

$$\begin{gathered} =\left(-\frac{2}{8}\right)\times \left(-\frac{2}{8}\right)\times \left(-\frac{2}{8}\right) \\ =-\frac{8}{512} \\ =-\frac{1}{64} \end{gathered}$$

Hence, the required value is $\left(-\frac{1}{64}\right)$ .
