How to find square root of any number easily?

Answer 1

hyy mate ✌️

Example 1: Find the √2401

Solution:

Step1: Decide the unit’s place of the result.

2401 ends with 1 = Square root will end with 1 or 9

_ 1 or _ 9

Step2: Leave the last 2 digits and find the immediate perfect square before the remaining number.

The immediate perfect square before 24 = 16, which is 42

That is the number in ten’s place

41 or 49

Step 3: To determine whether the square root of 2401 is 41 or 49Method 1: Take the number that lies exactly between 41 and 49 and square it.

452 = 2025 (We have learnt earlier how to find square of numbers ending with 5)

2025 < 2401

45 < Square root of 2401

And since

45 < 49

Square root of 2401 is 49
