What is the sum of the digits in the number 9886 when each digit is raised to the power of its position and added together?

To find the sum, we raise each digit to the power of its position and add them. 9^1 + 8^2 + 8^3 + 6^4 = 9 + 64 + 512 + 1296 = 1881. Therefore, the sum of the digits in the number 9886 is 1881.

Math question: What is the largest possible prime factor of the number 9886?

To find the largest prime factor of 9886, we can use prime factorization. The prime factorization of 9886 is 2 × 4943. Therefore, the largest prime factor of 9886 is 4943, a prime number. Prime factorization helps break down a number into its prime factors, which are the building blocks of the number.

Question: What is the sum of all positive odd numbers less than 9886 that are divisible by both 3 and 7?

To find the sum of positive odd numbers less than 9886 divisible by both 3 and 7, we need to determine the largest odd number divisible by 3 and 7. The largest odd number divisible by both 3 and 7 is 9867. To find the sum, we can use the formula for the sum of an arithmetic series: Sn = n/2 * (a + l) where Sn is the sum, n is the number of terms, a is the first term, and l is the last term. Here, a = 21 (the smallest odd number divisible by both 3 and 7) and l = 9867. To find n, we use the formula for the nth term of an arithmetic sequence: an = a + (n - 1)d where d is the common difference. Here, d = 42 (as the common difference between consecutive odd numbers divisible by 3 and 7 is 42). Solving for n: 9867 = 21 + (n - 1)42 9846 = (n - 1)42 n - 1 = 234 n = 235 Therefore, there are 235 odd numbers less than 9886 that are divisible by both 3 and 7. Substituting the values into the sum formula: Sn = 235/2 * (21 + 9867) Sn = 117.5 * 9888 Sn = 1,161,960 Hence, the sum of all positive odd numbers less than 9886 that are divisible by both 3 and 7 is 1,161,960.
