Question

find whether cube root of 2744 by using estiamating method​

Answer 1

Answer:

Step I: 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

Answer 2

Answer:

33

Step-by-step explanation:

first group number into two parts 27 , 44

then find the cube root of 27 it cube root is 3

then estimate the cube root of 44 by checking the number 44 line in which two cube root number 44 line between 3 and 4 S cube of 3 is 9 and 4 is 64 we will take smaller number cube root of 2744 is 33
