Math question: What is the sum of the squares of the digits in the number 9902?

To find the sum of the squares of the digits in the number 9902, we start by separating the digits: 9, 9, 0, and 2. Next, we square each digit: 9^2 = 81, 9^2 = 81, 0^2 = 0, and 2^2 = 4. Adding these results together, we have 81 + 81 + 0 + 4 = 166. Hence, the sum of the squares of the digits in 9902 is 166.

Question: What is the largest odd divisor of the number 9902?

To find the largest odd divisor of 9902, we must prime factorize it. Since 9902 is even, we can divide it by 2, resulting in 4951. To verify if 4951 is prime, we only need to check for divisors up to its square root, which is approximately 70. Calculating divisors from 3 to 70, we find that 7 is the largest divisor. Therefore, the largest odd divisor of 9902 is 7.

Math question: What is the sum of the digits of the number 9902?

To find the sum of the digits in 9902, we add the individual digits together. 9 + 9 + 0 + 2 = 20 So, the sum of the digits of the number 9902 is 20.
