Math question: If 1601 is multiplied by the sum of its digits, what is the result?

To find the sum of the digits of 1601, we add 1+6+0+1 = 8. Now, multiply 1601 by 8: 1601 * 8 = 12808. Therefore, the result is 12808.

Math Question: What is the remainder when 1601 is divided by the sum of the digits of its square?

To find the sum of the digits of the square of 1601, we first calculate the square as (1601)^2 = 2563201. The sum of the digits in this result is 2 + 5 + 6 + 3 + 2 + 0 + 1 = 19. Now, when we divide 1601 by 19, the quotient is 84 with a remainder of 5. Therefore, the remainder when 1601 is divided by the sum of the digits of its square is 5.

Question: What is the smallest prime number that can be expressed as the sum of two different perfect squares, both less than or equal to 1601?

By checking all possible combinations, we find that 1261 = 29^2 + 32^2 is the smallest prime number that fulfills the given condition. Being the sum of two perfect squares, it is expressed as the sum of 29^2 and 32^2, both less than or equal to 1601. Notably, 1261 is a prime number since it is only divisible by 1 and itself, and no other smaller prime numbers can satisfy the given criteria.
