Question

Find the largest number of 3 digits which is a perfect square.​

Answer 1

Answer:

961

Here we can see that 999 is not a perfect square as it leaves 38 as remainder. So if 38 will be added to 999 then it will become a 4 digit number. Therefore to find the largest 3 digit perfect square we will subtract 38 from 999. Hence 961 is the largest 3 digit perfect square whose square root is 31.

Answer 2

Answer:

961 is the largest number of 3 digits which is a perfect square of the number 31

Step-by-step explanation:

We know that the largest number of 3-digit is 999.

So,

To find the square root of number 999 then we have applied the long division method and check whether it is a perfect square or not.

Here,

we can see that 999 is not a perfect square as it leaves 38 as the remainder.

So,

if 38 will be added to 999 then it will become a 4 digit number.

Therefore, to find the largest 3 digit perfect square we will subtract 38 from 999.

999 - 38 = 961.

Hence, 961 is the largest 3 digit perfect square whose square root is 31.
