1.	Find the largest number of 3 digits which is a perfect square.
Answer» At first, The largest 3 digit number = 999 Now, The number whose square is 999 is 31.61 (approx.) Hence, The square of any number greater than 31.61 would be a 4-digit number. Therefore, The square of 31 will be the greatest 3 digit perfect square. We can calculate the largest 3 digit perfect square number as: 31² = 31 × 31 = 961

Answer»

At first,

The largest 3 digit number = 999

Now,

The number whose square is 999 is 31.61 (approx.)

Hence,

The square of any number greater than 31.61 would be a 4-digit number.

Therefore,

The square of 31 will be the greatest 3 digit perfect square.

We can calculate the largest 3 digit perfect square number as:

31² = 31 × 31

= 961
