Question 15 Marks
Find the least number which must be subtracted from $825$ so as to get a perfect square. Also find the square root of the perfect square so obtained.
Answer
This shows that $28$ is less than $825$ by $41$.
This means, if we subtract the remainder from the number, we get a perfect square,
So, the required least number is $41$.
Therefore, the required perfect square is $825 – 41 = 784$
Hence, $\sqrt {784} $$=28$.
