Math question: Can the number 1798 be expressed as the sum of two perfect squares?

To determine if 1798 can be expressed as the sum of two perfect squares, we can check if any perfect square less than 1798 can be subtracted from it to yield another perfect square. Since the largest perfect square less than 1798 is 42^2 = 1764, subtracting it from 1798 yields 34. However, 34 is not a perfect square. Hence, 1798 cannot be expressed as the sum of two perfect squares.

Math question: Given a number, 1798, what is the sum of its digits squared?

To find the sum of the digits squared for the number 1798, we first calculate the square of each individual digit. The digit 1 squared is 1, the digit 7 squared is 49, the digit 9 squared is 81, and the digit 8 squared is 64. Now, adding these squared values gives us 1 + 49 + 81 + 64 = 195. Therefore, the sum of the digits squared for the number 1798 is 195.

Math question: What is the sum of the prime factors of the number 1798?

To find the prime factors, we begin by dividing 1798 by its smallest prime factor, which is 2. 1798 ÷ 2 = 899. Next, we divide 899 by 2, resulting in 899 ÷ 2 = 449. Now, since 449 is a prime number, it becomes the largest prime factor of 1798. The sum of the prime factors is 2 + 449 = 451. Therefore, the sum of the prime factors of 1798 is 451.
