How to find cube root throgh estimation method ????

Step 1— Group the digits of the number into group 1 & 2

Step 2— Write the first three digits in the first group

Step 3— Write the remaining digits in the second group

Step 4— See the ones digit of the first group, and u can henceforth determine like this –

if it ends with "8" then the ones digit of the cube root must be "2"

if it ends with "1" then the ones digit of the cube root must be "1" and so on.

Step 5— In the last group, see what digit it is, and see it lies between which no.

for example, if the number in the group two is 28,

27 < 28 < 64

27 = 3^3
64 = 4^3

hence, the 2nd digit of the cube root is 3

TIP→ for this you need memorize cubes of all the numbers from 1 to 10

Here's a quick peak —→

8^3 = 512
13^3 = 2179
15^3 = 3375
18^3 = 5832
