Question

Answer 1

Answer:

the smallest no. to be added to it is 176 to get a perfect square

Answer 2

Answer:

If we square root 531, we will get the quotient as 23...

So, if we square 23 we will get 529 which is not applicable as the question states which is the smallest number that should be added

Hence, we will take the next number i.e 24

= 24² - 531​

= 576 - 531

= 45          

the smallest number to be added to get perfect square of 531 is 45.
