Math Question: What is the smallest positive integer greater than 2621 that is divisible evenly by both 7 and 9?

To find the smallest positive integer divisible by both 7 and 9, we need to find their least common multiple (LCM). The prime factorization of 7 is 7, and the prime factorization of 9 is 3^2. Since the LCM is the highest power of each prime factor in the factorizations, the LCM of 7 and 9 is 7 × 3^2 = 63. Therefore, by starting from 2621 and checking numbers one by one, the smallest number divisible by both 7 and 9 is 2646 (as 2646 ÷ 63 = 42).

Math question: What is the sum of the digits in the number 2621?

To find the sum of the digits in the number 2621, we add the individual digits together. So, 2 + 6 + 2 + 1 equals 11.

Math question: If 2621 is multiplied by 9 and divided by 3, then added to the square root of 2621, what is the result?

Let's solve step by step. First, multiply 2621 by 9: 2621 * 9 = 23,589. Next, divide this result by 3: 23,589 / 3 = 7,863. Finally, find the square root of 2621 ≈ 51.2 (approximated). Adding it to 7,863, the result is approximately 7,914.2 (approximated). Therefore, the answer is the result of 7,914.2 (approximated) when 2621 is multiplied by 9, divided by 3, and added to the square root of 2621.
