3. Find the least number which must be added to the following numbers to make them a perfect square. i) 37460 ii) 506900 iii) 4931 iv) 5607

i). 211.

ii). 711.

iii). 31

iv). 131.

Step-by-step explanation:

i). √37460 = 193.545

Then take the whole number from the decimal:

193² = 193 × 193 = 37249

You subtract the answer from the main number:

37460 - 37249 = 211

211 is the answer.

ii). √506900 = 711.969

711² = 711 × 711 = 505521

506900 - 505521 = 1379

1379 is the answer.

iii). √4931 = 70.221

70² = 70 × 70 = 4900

4931 - 4900 = 31

31 is the answer.

iv). √5607 = 74.879

74² = 74 × 74 = 5476

5607 - 5476 = 131

131 is the answer.
