Math question: If the number 6409 is multiplied by 3 and divided by the square root of 81, what is the final result?

To solve the problem, first find the square root of 81, which is 9. Then multiply 6409 by 3 to get 19227. Dividing this result by 9, we find that the final answer is 2136.3333 (rounded to 4 decimal places). Therefore, the final result when performing the calculations is approximately 2136.3333.

Question: What is the sum of the prime factors of the number 6409?

To find the prime factors of 6409, we first check if it is divisible by 2, 3, 5, and so on. After dividing by 7, we find that 6409 = 7 * 7 * 131. Therefore, the prime factors of 6409 are 7 and 131. The sum of these prime factors is 138.

Math question: If a number is formed by repeating the digits 6409, how many times does the digit 4 appear in that number?

To determine the number of times digit 4 appears in the number formed by repeating 6409, we first need to find the total number of digits. Since the number 6409 has 4 digits, we know that the repeating number will also have 4 digits. Thus, the number formed by repeating 6409 will look like this: 640964096409... As we observe, the digit 4 appears once in each repetition, so it will occur once for each repetition. As there are 4 digits in each repetition, and the repetition continues indefinitely, we can conclude that the digit 4 will appear an infinite number of times in this number.
