How to find square root of a number in a smart method is a 3-step process
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 49
Method 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
It can also be found by Prime Factorization...
