Question

$512$

Answer 1

Step $I$: Form groups of $3$ starting from right most digit of $512$, i.e. $\overline{512}$.

Then, the only group is $512$.

Here, $512$ has $3$ digit.

Step $II$: Take $512$.

Digit in unit place $=2$.

Therefore, we take one's place of required cube root as $8$ ....[Since, $8^3=512$].

$\therefore \sqrt[3]{3512}=8$.
