Answer 1

Answer:

Example 3: Find square root of 64 by repeated subtraction method. 

Solution: This proceeds as: 

Step 1: 64 - 1 = 63 

Step 2: 63 - 3 = 60 

Step 3: 60 - 5 = 55 

Step 4: 55 - 7 = 48 

Step 5: 48 - 9 = 41 

Step 6: 41 - 11 = 30 

Step 7: 30 - 13 = 17 

Step 8: 17 - 17 = 0 

As you can see that given number 64 was repeatedly subtracted by successive odd numbers (starting from 1) and we get zero in eighth step. Therefore 8 is the square root of 64 

Or we can also write it as: 

√� 64 � = 8
