Answer 2

Answer :-

Form groups of 3 starting from right most digit of 2744

The two groups are 744 and 2.

744 has 3 digit and 2 has 1.

Step II: Take 744

Digit at unit place =4

We take one's place of required cube root as 4

Step III: Take other group 2

1

3

=1 and 2

3

=8

Smallest number among 1 and 2 is 1.

∴ we take 1 as ten's place

∴

_/2744

=14
