4618+8 =4626

4618+6 =4624

we have to check with their square roots

square root (4634) =68.073

square root (4619) =67.963

square root(4626) =68.014

square root (4624) = 68

So the least number that must be added to 4618 to make a perfect square is 6 so option d is answer

Hope this will help you..

Answer 2

Answer:

4618 + 6 = 4624 is a perfect square.

√4624 = 68

Hence, option D - 6 is correct answer.

Step-by-step explanation:

Option A:

4618 + 16 = 4634

√4634 = 68.07

4634 is not a perfect square.

So, option A correct.

Option B:

4618 + 1 = 4619

√4619 = 67.96

4619 is not a perfect square.

So, option B is correct.

Option C:

4618 + 8 = 4626

√4626 = 68.014

4626 is not a perfect square.

So, option C is not correct.

Option D:

4618 + 6 = 4624 is a perfect square.

√4624 = 68

Hence, option D - 6 is correct answer.
