Question: How many ways can the number 8451 be rearranged if none of its digits can repeat?

To determine the number of ways, we consider that in the four-digit number 8451, the first place can be filled with any of the four digits (8, 4, 5, or 1). Once the first digit is chosen, the second place can be filled with any of the remaining three digits, then the third place with two remaining digits, and finally, the fourth place with the last remaining digit. Therefore, the total number of ways to rearrange the number 8451 is 4 × 3 × 2 × 1 = 24.

What is the sum of the digits in the number 8451?

To find the sum of the digits in a number, we add each digit together. For the number 8451, we add 8 + 4 + 5 + 1, which equals 18. Thus, the sum of the digits in 8451 is 18.

Math question: If you divide a number by 7, subtract 4 from the result, multiply by 3, and then add 5, you get 8451. What is the original number?

To find the original number, let's work backwards. Start by subtracting 5 from 8451, which gives 8446. Then, divide 8446 by 3, resulting in 2815.33. Now, add 4 to 2815.33, giving 2819.33. Finally, multiply 2819.33 by 7, giving approximately 19735.33. Thus, the original number is ~19735.33.
