Math question: What is the sum of the digits in the number 9862?

To find the sum of the digits in the number 9862, we add each digit individually. The digit 9 + digit 8 + digit 6 + digit 2 equals 25. Hence, the sum of the digits in the number 9862 is 25.

Question: What is the sum of the digits of the number 9862 multiplied by the quotient when it is divided by 3, and then subtracting the remainder when it is divided by 7, multiplied by 2 raised to the power of the last digit?

To find the sum of the digits of 9862, we have 9 + 8 + 6 + 2 = 25. Then, when dividing 9862 by 3, we get a quotient of 3287 with a remainder of 1. Subtracting the remainder when divided by 7, which is 3, we have 1 - 3 = -2. Finally, the last digit of 9862 is 2, and 2 raised to the power of 2 is 4. Therefore, the answer is 25 × (-2) × 4 = -200.

Question: What is the square root of the sum of the number 9862 and twice its reverse, divided by the product of its digits incremented by the result of subtracting the first digit from the average of the second and third digits?

To find the square root, we first compute the reverse of 9862 (i.e., 2689) and multiply it by 2, resulting in 5378. Adding this to 9862 gives us 15240. The product of the digits (9 * 8 * 6 * 2) is 864. Subtracting the first digit (9) from the average of second and third digits [(8 + 6) / 2 = 7], we get 7 - 9 = -2. Adding 1 to -2 gives -1. Now, dividing 15240 by -1 yields -15240. Finally, taking the square root of -15240 gives us an imaginary number, i.e., √(-15240) = √(-1 * 15240) = ±123.6009304i.
