Math Question: If I subtract 63 from a seven-digit number and then divide the result by 23, the quotient obtained is equal to the difference of 154 and 5 squared. What is the number?

Let's represent the unknown seven-digit number as ̶ ̶̶ ̶̶̶ ̶̶̶ ̶̶̶ ̶̶̶ ̶̶̶ ̶̶ N. According to the question, (N - 63) ÷ 23 = 154 - 5². Simplifying, we have (N - 63) ÷ 23 = 154 - 25. Combining like terms gives (N - 63) ÷ 23 = 129. To isolate N, we multiply both sides by 23, resulting in N - 63 = 2967. Adding 63 to both sides, we find N = 3030. Hence, the number is 3030.

What is the largest prime factor of 6841?

The largest prime factor of 6841 is 97. A prime factor is a prime number that can divide a given number without leaving a remainder. To find the largest prime factor of 6841, we can start by dividing it by the smallest prime number (2) and continue dividing by larger primes until we cannot divide anymore. After dividing 6841 by 2, we get 3420 remainder 1. Continuing the process, we divide 3420 by 2, then 1710 by 2, then 855 by 3, and finally 285 by 3. At this point, we have 95 left, and none of the primes divide evenly into it. Hence, the largest prime factor of 6841 is 97.

What is the square root of 6841 divided by the sum of the digits when 6841 is written in base 6?

To find the square root of 6841, we first convert 6841 to base 6, which is 110021. The sum of the digits in base 6 is 1+1+0+0+2+1 = 5. Therefore, the square root of 6841 divided by the sum of digits is √6841 / 5. Calculating this, the answer is approximately 15.297.
