Verified Answer
What least number must be added to 6072 to make it a perfect square?a)...
Calculation:
Here, 5929 < 6072 < 6084
⇒ (77)2 < 6072 < 782
Here, 6072 is much closer to 6084 than 5929
∴ We will subtract 6072 from 6084 to get the required number,
⇒ (6084 - 6072) = 12
∴ When we add 12 to 6072, we get 6084, which is perfect square of 78.
∴ Required number is 12.
