Question

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

Answer 1

There are 10 squares of 3 digits : 144, 196, 256, 324, 400, 484, 576, 676, 784, 900

Answer 2

Answer:

961

Step-by-step explanation:

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.
