Answer 2

Step-by-step explanation:

Step I: Form groups of 3 starting from right most digit of 2197, i.e. 2197.

Then, the two groups are 2 and 197.

Here, 2 has 1 digit and 197 has 3 digit.

Step II: Take 197.

Digit in unit place =7.

Therefore, we take one's place of required cube root as 3 ....[Since, 33=27].

Step III: Now, take the other group 2.

We know, 13=1 and 23=8.

Here, the smallest number among 1 and 2 is 1.

Therefore, we take 1 as ten's place.

∴32197=13.
