$\underline{\underline{\huge{\textbf{Solution:}}}}$

$\underline{\large{\textbf{Step-1 }}}$
Check whether the greatest 4-digit No. is a Perfect Square

- Greatest 4-digit No. is 9999

- Find the Square root of 9999 using Division method.

case-1(i):
If Remainder = 0,
Then 9999 is a Perfect Square.

case-2(ii):
If the Remainder $\neq$ 0,
Then 9999 is not a Perfect Square.

$\underline{\large{\textbf{Step-2}}}$
Find the greatest 4-digit No. is a Perfect Square.

Incase of Remainder $\neq$ 0,
Subtract the Remainder from the dividend(9999) to get the perfect square

Here,
Remainder = 198

Therefore,
Greatest 4-digit number which is a perfect square = 9999 - 198 = 9801

$\underline{\large{\textbf{Step-3}}}$
Find the Square root of the perfect square obtained.

The square root of perfect square obtained is the quotient obtained in the division while finding square root

Therefore,
Square Root of 9801 = 99.
