Question

Find the greatest 5 digit number which is a perfect square.find iys square root.

Answer 1

We know that the largest 5 digit number is 99999. So let us check whether it is a perfect or not ?

So here we can see that 99999 is not a perfect square as it leaves 143 as the remainder while finding it s square root.

So for finding 5 digit perfect square we will have to subtract 143 from 99999

=> 99999-143 = 99856

Hence 99856 is a perfect square whose square root is √99856 = 316.

 

Answer 2

Answer: Its square root is 316.

Step-by-step explanation: According to the question,

As the greatest 5-digit number, which is a perfect square.

As the greatest 5-digit number =99999

As we need to find the smallest number that must be subtracted from, 99999 to get a perfect square,

As by the division method, we can get the remainder is 143.

So here we can see that 99999 is not a perfect square as it leaves 143 as the remainder while finding its square root

So if we subtract 143 from 99999, we will get a perfect square,

As the largest 5-digit perfect square = 99999-143 = 99856

As we have to find the perfect square's root = $\sqrt{99856} = 316$

Hence, Its square root is 316.
