What is the sum of all the odd multiples of 9 between 1 and 1494, inclusive?

To find the sum of odd multiples of 9, we need to determine the number of terms first. The first odd multiple is 9 itself, and the last odd multiple less than or equal to 1494 is 1485. Using the formula for the sum of an arithmetic series, Sn = (n/2)(2a + (n-1)d), where a is the first term, d is the common difference, and n is the number of terms, we can calculate the number of terms. Here, a = 9, d = 18 (common difference between odd multiples), and Sn = 1494. 1494 = (n/2)(2(9) + (n-1)(18)) Simplifying, we get: 1494 = 9n + 18(n-1) 1494 = 9n + 18n - 18 1494 = 27n - 18 1512 = 27n n = 1512 / 27 n = 56 So, there are 56 odd multiples of 9. Now to find the sum, we again use the formula Sn = (n/2)(2a + (n-1)d), where a = 9, d = 18, and n = 56. Sn = (56/2)(2(9) + (56-1)(18)) Sn = 28(18 + 1050) Sn = 28(1068) Sn = 29904 Therefore, the sum of all the odd multiples of 9 between 1 and 1494 is 29904.

Question: What is the sum of the digits of the number 1494 when each digit is raised to the power of its respective place value?

To find the sum of the digits of 1494 raised to the power of their respective place values, we break down the number 1494 into its individual digits. The first digit is 1, raised to the power of 3 (thousands place), which equals 1. The second digit is 4, raised to the power of 2 (hundreds place), which equals 16. The third digit is 9, raised to the power of 1 (tens place), which equals 9. The last digit is 4, raised to the power of 0 (ones place), which equals 1. Now, we add up these results: 1 + 16 + 9 + 1 = 27. Therefore, the sum of the digits of 1494 when each digit is raised to the power of its respective place value is 27.

What is the sum of the digits of the number 1494 if each digit is raised to the power of its place value position (from left to right)?

The sum of the digits of the number 1494, raised to the power of their place value positions, is calculated as (1^1) + (4^2) + (9^3) + (4^4) = 1 + 16 + 729 + 256 = 1002.
