Math question: What is the result of adding 8215 to its square root, dividing the sum by 2, and then subtracting 8215?

To find the answer, we first need to calculate the square root of 8215, which is approximately 90.661 (*calculations below). Adding this square root to 8215 gives us 8305.661. Dividing this sum by 2 yields 4152.8305, and finally, subtracting 8215 from this result gives -4062.1695. Therefore, the answer is -4062.1695. Calculation: √8215 ≈ 90.661 8215 + 90.661 = 8305.661 8305.661 ÷ 2 = 4152.8305 4152.8305 - 8215 = -4062.1695

What is the sum of the nearest odd numbers to the right and left of 8215 whose digits add up to an even number?

In order to find the nearest odd numbers with a digit sum that is even, we need to look for odd numbers whose digits form an even sum. The largest odd number to the right of 8215 with an even sum is 8221 (since 8 + 2 + 2 + 1 = 13, which is odd). The largest odd number to the left with an even sum is 8215 itself. Therefore, the sum of these numbers would be 8215 + 8221 = 16436.

Math Question: Can the number 8215 be evenly divided by any single digit prime number?

No, the number 8215 cannot be evenly divided by any single digit prime number. The prime numbers less than 10 are 2, 3, 5, and 7. When dividing 8215 by each of these numbers, we find: 8215 ÷ 2 = 4107.5 (not an integer), 8215 ÷ 3 = 2738.33333... (not an integer), 8215 ÷ 5 = 1643 (not an integer), 8215 ÷ 7 = 1173.57143... (not an integer). In all cases, the result is not a whole number, indicating that the number 8215 cannot be divided evenly by any single digit prime number.
