Question

by the method of finding units and tense digit of cube roots find the cube root of each of the following (a)4913​

Answer 1

Answer:

17

Step-by-step explanation:

Step I: Form groups of 3 starting from right most digit of 4913, i.e.

4

913

.

Then, the two groups are 4 and 913.

Here, 4 has only 1 digit and 913 has 3 digit.

Step II: Take 913.

Digit in unit place =3.

Therefore, we take one's place of required cube root as 7 ....[Since, 7

3

=343].

Step III: Now, take the other group 4.

We know, 1

3

=1 and 2

3

=8.

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

Therefore, we take 1 as ten's place.

∴

3

4913

=17.
