Question: What is the sum of the digits of the number 7209 multiplied by the square root of the number obtained by reversing the order of its digits?

To find the sum of the digits of 7209, we add 7 + 2 + 0 + 9 = 18. Reversing the digits gives us 9027. The square root of 9027 is approximately 94.997. Multiplying 18 by 94.997 gives us 1709.946. Therefore, the answer is 1709.946.

Math Question: If a number is divisible by 3 and 7, and its digit sum is 18, what is the sum of the smallest three-digit number meeting these conditions and the number 7209?

To find the smallest three-digit number divisible by 3 and 7, we must find their least common multiple (LCM), which is 21. The smallest three-digit multiple of 21 is 105. Now, let's consider the digit sum. If the digit sum is 18, we know that one of the digits needs to be 9. The remaining digits need to sum up to 9. Therefore, the smallest three-digit number meeting all these conditions is 909. Now, to find the sum of 7209 and 909, we add them together: 7209 + 909 ------ 8118 So, the sum of 7209 and the smallest three-digit number satisfying the given conditions is 8118.

Math question: What is the sum of the digits of the number 7209?

To find the sum of the digits, we can split the number 7209 into its individual digits: 7, 2, 0, and 9. Adding these together, we get 7 + 2 + 0 + 9 = 18. Therefore, the sum of the digits of 7209 is 18.
