Question: What is the square root of the sum of the digits of 3909, multiplied by the cube root of twice the number formed by reversing the digits of 3909, divided by the largest prime number less than 3909?

To find the square root of the sum of the digits of 3909, we add 3 + 9 + 0 + 9 = 21, so √21. Reversing the digits of 3909, we get 9093. Twice this number is 2 * 9093 = 18186. The cube root of 18186 is ∛18186. Now, we need to find the largest prime number less than 3909, which is 3889. Therefore, the final calculation becomes (√21) * (∛18186) / 3889 = 4.5824. Hence, the answer is approximately 4.5824.

Math question: What is the sum of all the even digits in the number 3909?

To find the sum of the even digits in 3909, we need to identify the even digits first. In this case, there are no even digits (0 and 9 are odd numbers). Therefore, the sum of the even digits in 3909 is 0.

Math question: What is the sum of the digits in the number 3909?

To find the sum of the digits in the number 3909, we add the individual digits together. Breaking the number down into its digits gives us 3, 9, 0, and 9. Summing these digits gives us 3 + 9 + 0 + 9 = 21. Thus, the sum of the digits in 3909 is 21.
