.Smallest number which must be added in 7581 to get a perfect square number. pl explain step by step​

Answer 1

The smallest no. which must be added to 7581 to get a perfect square will be 163.

We have to first find the square root of 7581 up to 2 decimal places.

Then the no. we get will be 87.01 ..... Then we have to just find the square of the number we have got + 1 and then find the square if that number. The no. we thus get will be 7744. Then just simply subtract 7581 from 7744 and you will get the answer.
