of this number.​

Answer 1

Answer:

100489

Step-by-step explanation:

Find the square root of 100000 which is 316.2. Take the next higher number which is 317. Find the square of 317 = 100489. So the smallest 6-digit number which is a perfect square = 100489.

Answer 2

• Let us try 999999. The square root of 999999 = 999.9995, which is not a perfect square root.

• The nearest number is 999 and its square = 998001.

• The greatest 6-digit number that is a perfect square is 998001 and its square root is 999
