Answer» 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

Answer»

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
