Final answer:
No, 25 is not a perfect square. However, it can be expressed as the sum of two identical perfect squares - 5² + 5²= 25.
Step-by-step explanation:
No, 25 is not a perfect square. A perfect square is a number that can be expressed as the square of an integer. Examples of perfect squares are 4 = 2², 9 = 3², and 16 = 4². Since 25 is 5², it is indeed a perfect square.
Now, let's check if 25 can be expressed as the sum of two other perfect squares. It cannot be expressed as the sum of two different perfect squares, but it can be expressed as the sum of the same perfect square, which is 5² + 5² = 25.
