Question

Find the least number of six digits which is a perfect square. Find the square root
of this number.​

Answer 1

Answer:

For that, we have to find the square root of 100000 by the long division method as follows: 100000 is 489 (4389 − 3900) less than 3172. Hence, to be a perfect square, 489 should be added to 100000. Hence, the least number of six digits that is a perfect square is 100489.

Answer 2

100489

For that, we have to find the square root of 100000 by the long division method as follows: 100000 is 489 (4389 − 3900) less than 3172. Hence, to be a perfect square, 489 should be added to 100000. Hence, the least number of six digits that is a perfect square is 100489.
