Answer 1

hye

===================


 the least 6 digit number is 100000

=> we have to Find  the square root of 100000

=> √100000 = 316.227766

=> So, to find the required answer, we need to take the next number of 316.227766.

=> that is we have to round of to the nearest ten 

=> That is 317.

=> now we he to find the square of 317. [that is 317×317 ]

=> 317×317 = 100489

Therefore, 100489 is least 6 digit number which is a perfect square. 

now lets find the square root of   100489

=>√ 100489 =  317

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
