7 and 10

Step-by-step explanation:

1. 49-1 = 48

2. 48-3 = 45

3. 45-5 = 40

4. 40-7 = 33

5. 33-9 = 24

6. 24-11 = 13

7. 13- 13 = 0

Thus, we have subtracted consecutive odd numbers from 49 starting from 1. 0 is obtained in the 7th step. So we have √49 = 7.

2. 100

1. 100-1= 99

2. 99-3 = 96

3. 96-5= 91

4. 91-7 = 84

5. 84-9 = 75

6. 75-11 = 64

7. 64-13 = 51

8. 51-15 = 36

9. 36-17 = 19

10. 19-19 = 0

Thus, we have subtracted consecutive odd numbers from 100 starting from 1. 0 is obtained in the 10th step. So we have √100 = 10.
