Answer 1

Hey mate
Here is your answer

24 should be added to 6865 to make it perfect square

6865+24=6889

6889 is square of 83

Answer 2

Answer:

WE KNOW

6724<6865<6889

82²<6865<83²

SO ADDING A NO. MUST MAKE 6865 A PERFECT SQUARE.

SO THE NO. IS 6889-6865=24

SO ADDING 24 TO 6865 IT BECOMES 6889 WHICH IS A PERFECT SQUARE OF 83.
