Question

Convert into power notation
$\frac{-27}{125}$

Answer 1

Given number is $\frac{-27}{125}$

We can write $-27$ as $(-3)\times (-3)\times (-3)$ which is $(-3{)}^3$.

Similarly, we can write $125$ as $\left(5\right)\times \left(5\right)\times \left(5\right)$ which is $(5{)}^3$.

$\therefore \frac{-27}{125}={\left[\frac{-3}{5}\right]}^3$
