HERE GOES YOUR ANS

•    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 = 225
•    Step 9: 225 - 17 = 208
•    Step 10: 208 - 19 = 189
•    Step 11: 189 - 21 = 168
•    Step 12: 168 - 23 = 145
•    Step 13: 145 - 25 = 120
•    Step 14: 120 - 27= 93
•    Step 15: 93 - 29 = 64
•    Step 16: 64-31 =33
•    Step 17:33-33=0

We get zero in seventeenth step. Therefore 17 is the square root of 289.
