Math question: What is the sum of the digits when the number 2143 is multiplied by 3 and then divided by 7?

To find the sum of the digits when 2143 is multiplied by 3 and divided by 7, we start by multiplying 2143 by 3 to get 6429. Then, we divide 6429 by 7 to obtain the quotient 918 remainder 3. The sum of the quotient's digits (9+1+8=18) is 18. Therefore, the answer is 18.

Math question: By arranging the digits of the number 2143 in different ways, how many unique 4-digit numbers can be formed?

To calculate the number of unique 4-digit numbers that can be formed from the digits of 2143, we can use the concept of permutations. Let's break it down step by step: 1. Since we have 4 distinct digits (2, 1, 4, and 3), we have 4 choices for the first digit. 2. Once the first digit is chosen, we have 3 remaining digits to choose from for the second digit. 3. After both the first and second digits are selected, we have 2 choices left for the third digit. 4. Finally, the last remaining digit will fill the last place. To find the total number of unique 4-digit numbers, we multiply these choices together: 4 choices for the first digit × 3 choices for the second digit × 2 choices for the third digit × 1 choice for the fourth digit = 4 × 3 × 2 × 1 = 24. Thus, the answer is that by arranging the digits of the number 2143, we can form 24 unique 4-digit numbers.

Question: What is the sum of the digits in the number 2143 when each digit is raised to the power of its respective position and added together?

To find the sum of the digits in 2143 raised to the power of their respective positions, we split the number as 2^4 + 1^3 + 4^2 + 3^1. Solving, we get 16 + 1 + 16 + 3 = 36. Therefore, the sum of the digits in the number 2143, when each digit is raised to the power of its respective position and added together, is 36.
