Question

If n is a two digit perfect square number .find n so that sum of their two digits becomes maximum

Answer 1

Answer:

Step-by-step explanation:

The answer is 49.

Because:

1. It is a perfect square number.

2. When we add 4 and 9 we get 13 which is the highest number that we'll get when we add the 2 digits of a "2 digit perfect square number."

For example:

1. 81 (9²)

      8+1=9

2. 64 (8²)

      6+4=10

3. 36 (6²)

      3+6=9
