Question

8. Find the least number that must be subtracted from 1525 to make
a perfect Square? And also find
Square root of perfect square number so obtained

​

Answer 1

Let us take the square root of 1525

3    15  25   39

       9

69     625

          621

           4

We observe that, 39² < 1525

Therefore, to get a perfect square, 4 must be subtracted from 1525.

Therefore the required perfect square = 1525 – 4 = 1521
