To find out if a number is a square number, find its prime factors and check if all prime factors duplicate. In this example, the prime factors are: 2,2,5,5,5,5 We can see that all numbers are duplicates, and can be paired up. So 2500 is a square number of 2x5x5 or 50.
1000 + 2500 = 2500
22*54 = 2500
As a product of its prime factors: 2*2*5*5*5*5 = 2500 or 2^2 times 5^4 = 2500

No, it is composite.
No.
22*54 = 2500
As a product of its prime factors: 2*2*5*5*5*5 = 2500 or 2^2 times 5^4 = 2500
As a product of its prime factors: 2*2*5*5*5*5 = 2500
As a product of its prime factors: 2*2*5*5*5*5 = 2500
The factors of 2500 are 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500, 625, 1250, and 2500. The prime factors of 2500 are 2, 2, 5, 5, 5, and 5. The distinct prime factors of 2500 are 2 and 5. The prime factorization of 2500 is 2 x 2 x 5 x 5 x 5 x 5.

2500 is a composite number. A prime number has exactly 2 factors, 1 and the number itself. All even numbers greater than 2 (numbers ending in 2, 4, 6, 8, or 0) are composites because they have more than 2 factors.
