Question

13) Find the smallest number that must be added to 18625 to make it a perfect square​

Answer 1

$\underline{ \underline{ \bold{ \large{ \: Answer \: : \: \: \: }}}}$

$\to$ 504

$\underline{ \underline{ \bold{ \large{ \: \: Explanation : \: \: \: }}}}$

$\to \sqrt{18265 \: } = 136.47$

That means next perfect square is ( 137 )²

$\to$ ( 137 )² = 18769

Smallest number that must be added to get a perfect square is :

$\to$ 18769 - 18265

$\to$ 504
