HELP

solve this question fully

Answer 1

Solution: This proceeds as:

Step 1: 49 - 1 = 48

Step 2:48 - 3 = 45

Step 3: 45 - 5 = 40

Step 4: 40 - 7 = 33

Step 5: 33 - 9 = 24

Step 6: 24 - 11 = 13

Step 7: 13 - 13 = 0

As you can see that given number 49 was repeatedly subtracted by successive odd numbers (starting from 1) and we get zero in seventh step. Therefore 7 is the square root of 49

Or we can also write it as:

√49 = 7
