Question

What is the minimum number to be added to 1289 so that it becomes a perfect square?

A.

1

B.

7

C.

13

D.

16

Correct option is B

To find the minimum number that must be added to 1289 to make it a perfect square, follow these steps:

  1. Find the square root of 1289:

    • √1289 ≈ 35.91 (not a whole number, meaning 1289 is not a perfect square)
  2. Identify the next perfect square:

    • The next perfect square greater than 1289 is 36² = 1296.
  3. Determine the required addition:

    • 1296 - 1289 = 7

Thus, the minimum number to be added to 1289 to make it a perfect square is 7.
