Math Question: In a given number, 3685, what is the sum of the digits multiplied by the product of the digits? Math

To find the sum of the digits, we add 3 + 6 + 8 + 5 = 22. Multiplying the digits together, we have 3 × 6 × 8 × 5 = 720. Therefore, the answer to the question is 22 multiplied by 720, which equals 15,840.

Math question: What is the closest perfect square to the number 3685?

To find the closest perfect square to 3685, we need to determine the perfect squares near it. The perfect square less than 3685 is 3600 (60^2) and the perfect square greater than 3685 is 3721 (61^2). Therefore, the closest perfect square to 3685 is 3600.

Question: If the digits of a four-digit number are rearranged to form the number 3685, what is the largest possible three-digit number that can be subtracted from it?

To find the largest three-digit number that can be subtracted from 3685, we must rearrange the digits to form the smallest possible four-digit number. The smallest four-digit number that can be formed using these digits is 3568 (since 3 is the smallest leading digit). Subtracting this from 3685 yields the largest possible three-digit number, which is 127.
