Respuesta :

The square root must be between the square roots of the perfect squares just above and just below your number. 

For example the square root of 89 must be between 9 and 10.

To estimate the square root of non-perfect squared numbers we have to check the number with a near-perfect squared number.

Let us take some examples to understand it in a better way. Following are the examples:

(1) Find the square root of 63.

Now, the nearest perfect square number is 64, and the value of its square root is 8. Thus, we can the value of the square root of 63 as 7.98.

(2) Find the square root of 129.

Now, the nearest perfect square number is 121, and the value of its square root is 11. Thus, we can estimate the value of the square root of 129 as 11.29.
