Answer 2

Given,

The given number$\[ = 1280\]$

Solution,

Know that $\[{4^3} = 64.\]$

Understand here we have to calculate the smallest number by which $\[1280\]$ must be divided to get a perfect cube.

Therefore,

$\[\begin{array}{l} \Rightarrow \frac{{1280}}{{20}}\\ \Rightarrow 64\\ \Rightarrow {4^3}\end{array}\]$

Hence, the cube root of the perfect cube so obtained is $\[4.\]$
