To find:

Square numbers

Solution:

The given numbers are 15, 36, 48, 64, 80.

From the given numbers, we need to find the square numbers.

• Square numbers never end with 2, 3, 7, or 8.

• The perfect Square number ends with 0, 1, 4, 5, 6, and 9.

• The number of zeros at the end of a square number is always even.

• A number ending with an odd number of zeros is never a perfect square.

The first 10 square numbers are:

1² = 1

2² = 4

3² = 9

4² = 16

5² = 25

6² = 36

7² = 49

8² = 64

9² = 81

10² = 100

Hence, from the above, we can conclude that 36 and 64 are square numbers.
