Question: What is the sum of the digits in the number 7158?

To find the sum of the digits in 7158, we add the individual digits together. Since 7 + 1 + 5 + 8 = 21, the sum of the digits in 7158 is 21.

Math question: What is the value obtained by subtracting the sum of the digits in 7158 from their product, divided by the difference between their largest and smallest digits, all squared?

To find the answer, we'll start by summing the digits of 7158, which gives us 7 + 1 + 5 + 8 = 21. Next, we'll calculate their product, which equals 7 * 1 * 5 * 8 = 280. Then, we find the difference between the largest and smallest digits (8 - 1 = 7). Now, dividing the product by the difference gives 280 ÷ 7 = 40. Finally, we'll square this value, resulting in 40^2 = 1600. Therefore, the answer is 1600.

What is the largest two-digit prime number that can be formed using the digits of the number 7158?

To find the largest two-digit prime number, we need to consider the possible combinations of the digits 7, 1, 5, and 8. The largest two-digit number that can be formed is 87, but it is not prime. The next largest is 78, which is divisible by 2, making it non-prime as well. Moving ahead, we have 75, which is divisible by 5, again making it non-prime. Finally, we have 58, which is not divisible by 2 or 5, and hence is prime. Therefore, the largest two-digit prime number that can be formed using the digits of 7158 is 58.
