ok I am right

Answer 2

Answer:

The long division method for √7921 can be found as

square root of 7921

Hence, √7921 = 89

Since, 7921 is a perfect square, therefore, we can also find using factorisation method.

7921 = 89 x 89

Example 2: Now if we have to find the square root of 2, then it is difficult to find using factorisation method. Hence, we can determine √2 using long division method, as given below:

Square root of 2

We can proceed further to more decimal places. Here we have derived √2 value upto four places of decimals.

Hence √2 = 1.4142..
