Question

estimate the cube root of 40522 method​

Answer 1

Answer:

The cube root of the number 40522 is 38

Step-by-step explanation:

To find the cube root of the given number 40522,

First make the given number as a group of three.

So we have 40 and 522

In the first group we have 522

The unit digit of the first group is 2

Therefore, the unit digit of the cube root will be 8

In the second group we have 40

But 40 is not a perfect cube

It lies between 3 cube and 4 cube

3 is smaller than 4

Therefore the tens digit of the cube root will be 3.

Hence,

Cube root of 40522 is 38
