Math question: What is the smallest prime number that can be formed by rearranging the digits of the number 7946?

To find the smallest prime number formed by rearranging the digits of 7946, we can generate all possible combinations of the digits. Rearranging them, we get 7946, 7964, 7694, 7649, 7496, 7469, 9764, 9746, 9674, 9647, 9476, 9467, 7964, 7946, 7694, 7649, 7496, 7469, and so on. Now, we need to check each number for primality. After checking all the combinations, we find that the smallest prime number is 7649.

Question: If a number is multiplied by 3, then divided by 2, and the result is subtracted by 2294, what is the value obtained if the number is 7946?

To find the value when 7946 is multiplied by 3, we get 23838. Dividing 23838 by 2 gives us 11919. Finally, subtracting 2294 from 11919 results in 9625. Therefore, when the number 7946 undergoes the given operations, the final value obtained is 9625.

What is the sum of the digits of the number 7946 multiplied by the difference between the hundreds and tens digits of the number squared?

To solve this, we need to break down the number 7946. The sum of its digits is 7 + 9 + 4 + 6 = 26. The hundreds digit is 7 and the tens digit is 9, so the difference between them is 7 - 9 = -2. Squaring -2 gives us (-2)^2 = 4. Finally, multiplying 26 by 4 gives us 26 × 4 = 104. Therefore, the answer is 104.
