Answer:
225=15²
Step-by-step explanation:
step1: 225-1 =224
step2: 224-3 =221
step3: 221-5 =216
step4: 216-7 =209
step5: 209-9 =200
step6: 200-11 =189
step7: 189-13 =176
step8: 176-15 =161
step9: 161-17 =144
step10: 144-19=125
step11: 125-21 =104
step12:104-23 = 81
step13: 81-25 =56
step14: 56-27 =29
step15: 29-29 =0
here we got 0 in 15th step so √225=15
