Math question: How many unique three-digit numbers can be formed using the digits of the number 8557?

To find the number of unique three-digit numbers, we need to consider the restriction that the first digit cannot be zero. As there are three distinct digits (8, 5, and 7), we have three choices for the first digit, two choices for the second digit (excluding the chosen first digit), and only one choice for the third digit. By multiplying these choices, we get a total of 3 × 2 × 1 = 6 unique three-digit numbers that can be formed using the digits of the number 8557. Therefore, there are 6 unique three-digit numbers that can be formed.

Math question: What is the sum of the digits of the number 8557 when each digit is raised to the power of its position and then added together?

To find the sum of the digits, we raise each digit to the power of its position and add them. For 8557: 8^1 = 8, 5^2 = 25, 5^3 = 125, 7^4 = 2401. Hence, the sum of the digits = 8 + 25 + 125 + 2401 = 2559. Explanation: We manipulated the given number by raising each digit to its position's power, i.e., the units digit to the power of 1, tens digit to the power of 2, hundreds digit to the power of 3, and so on. Then, we added all these values together to get the sum of the digits, which in this case is 2559.

What is the remainder when 8557 is divided by the sum of its digits?

To find the sum of the digits of 8557, we add 8 + 5 + 5 + 7 = 25. When we divide 8557 by 25, the quotient is 342 with a remainder of 7. Therefore, the remainder when 8557 is divided by the sum of its digits is 7.
