Answer 2

Answer:

√121=11&√169=13

Step-by-step explanation:

1.121-1=120

2.120-3=117

3.117-5=112

4.112-7=105

5.105-9=96

6.96-11=85

7.85-13=72

8.72-15=57

9.57-17=40

10.40-19=21

11.21-21=0

so we get 0 in 11 steps

so √121=11

and finding√169

1.169-1=168

2.168-3=165

3.165-5=160

4.160-7=153

5.153-9=144

6.144-11=133

7.133-13=120

8.120-15=105

9.105-17=88

10.88-19=69

11.69-21=48

12.48-23=25

13.25-25=0

zero comes in 13 steps

so √169=13
