Question

Find the square root by repeated subtraction method (¡) 144 (¡¡) 289​

Answer 1

Step-by-step explanation:

1.44−1=143

2.143−3=140,

3.140−5=135

4.135−7=128,

5.128−9=119,

6.119−11=108,

7.108−13=95,

8.95−15=80,

9.80−17=63,

10.63−19=44,

11.44−21=23,

12.23−23=0

∴

144

=12.

Step 1: 289 - 1 = 288.

Step 2: 288 - 3 = 285.

Step 3: 285 - 5 = 280.

Step 4: 280 - 7 = 273.

Step 5: 273 - 9 = 264.

Step 6: 264 - 11 = 253.

Step 7: 253 - 13 = 240.

Step 8: 240 - 15 = 235.

Step 9: 235- 17=218

Step 10:218-19=199

step 11: 199-21=178

step 12: 178-23=155

step13: 155-25 =130

step 14: 130-27=103

step 15: 103-29 =74

step 16: 74-31=43

step 17: 43-43 =0

289 =17
