Question

Find the cube root of 24389 by long division method with full explain​

Answer 1

Answer:

Step I: Form groups of 3 starting from right most digit of 24389, i.e. 24389.

Then, the two groups are 24 and 389.

Here, 24 has 2 digit and 389 has 3 digit.

Step II: Take 389.

Digit in unit place =9.

Therefore, we take one's place of required cube root as 9 ....[Since, 93=729].

Step III: Now, take the other group 24.

We know, 33=27 and 23=84.

Here, the smallest number among 3 and 2 is 2.

Therefore, we take 2 as ten's place.

∴324389=29.
