Answer 1

Step-by-step explanation:

9 is the least number to be added to get a perfect square

2491+9=2500 = 50^2

Answer 2

Answer:

9

Step-by-step explanation:

Break 2491 in pair of 2 like 24 and 91

4 9

----------------

4 | 24 91

| 16

|---------------

89 | 8 91

8 01

--------------

0 90

The questioint is 49, so,

(49)^2 = 2401 < 2491

(50)^2 = 2500 > 2491

Therefore, 2500 - 2491 = 9

So, least no. to be added to 2491 to make it a perfect square is 9
