Step-by-step explanation:

Concept:

A number from a given number system that can be written as the square of another number from the same number system is said to be a perfect square.

Given:

Count to be added with $=630$

To find:

We have to find the smallest number must be added to $630$ to make the perfect square

Solution:

We know that square of $25$ is $625$ but the count we have is $630$ it means that the next number from $25$ provides us the least count that should be added in $630$.

The square of $26$ is $676$, so The least count is,

$676-630=46$

$46$ is the least number to be added.

Thus, $676$ is the perfect square.

Square root of $\sqrt{676}=26$
