Math question: If 2195 is equal to the sum of three consecutive odd numbers, what are those three numbers?

Let's assume the first odd number is x. Since the numbers are consecutive, the second odd number would be (x + 2) and the third odd number would be (x + 4). According to the given information, the sum of these three numbers is 2195. Therefore, the equation would be: x + (x + 2) + (x + 4) = 2195. Solving this equation yields x = 729. So, the three consecutive odd numbers are 729, 731, and 733, summing up to the given 2195.

Math question: What is the sum of the digits in the number 2195?

The number 2195 consists of four digits: 2, 1, 9, and 5. To find the sum of these digits, we add them together: 2 + 1 + 9 + 5 = 17. Therefore, the sum of the digits in the number 2195 is 17.

Math question: What is the smallest positive integer that, when multiplied by 2195, results in a perfect square?

To determine the smallest positive integer that yields a perfect square when multiplied by 2195, we need to prime factorize it. Prime factorizing 2195, we find 2195 = 5 × 439. Notice that the prime factorization does not contain any pairs of identical primes, which means it is not a perfect square itself. Therefore, we need to multiply 2195 by an extra prime or primes to make a perfect square. We can add the missing prime factors from the prime factorization to achieve a perfect square, which requires multiplying 2195 by 439 since 439 is already a prime. Therefore, the smallest positive integer that satisfies the condition is 439.
