Math question: If a certain number is formed by placing the digits 8, 4, 5, and 6 in a particular order, how many possible arrangements can be made?

To find the number of possible arrangements, we use the concept of permutations. Since there are 4 distinct digits, we have 4 options for the first position, then 3 options for the second position, 2 options for the third position, and 1 option for the last position. Thus, the number of arrangements is: 4 × 3 × 2 × 1 = 24 Therefore, there are 24 possible arrangements of the digits 8, 4, 5, and 6 when forming a number.

What is the sum of the digits in the number 8456 when each digit is raised to the power of its respective place value (e.g., 8^1 + 4^2 + 5^3 + 6^4)?

When we calculate the individual powers of each digit in 8456, we get 8^1 = 8, 4^2 = 16, 5^3 = 125, and 6^4 = 1296. Adding these values together gives us 8 + 16 + 125 + 1296 = 1445. Thus, the sum of the digits in 8456 when raised to the power of their respective place values is 1445.

Question: What is the value obtained by multiplying the sum of the digits of the number 8456 by the square of the difference between the first and last digit?

To find the value, we start by calculating the sum of the digits of 8456. The sum is 8 + 4 + 5 + 6 = 23. Next, we calculate the square of the difference between the first and last digit: (8 - 6)^2 = 4^2 = 16. Finally, we multiply these two values together: 23 * 16 = 368. Therefore, the value obtained is 368.
