Math question: The number 7146 is rounded to the nearest thousand. What is this rounded value?

To round a number to the nearest thousand, we need to look at the hundreds digit. In this case, the hundreds digit is 1. Since it is less than 5, we must round down. Therefore, when rounding 7146 to the nearest thousand, the rounded value is 7000.

What is the sum of the digits when the number 7146 is multiplied by its own reverse, rounded to the nearest whole number, and then divided by the product of the middle two digits subtracted by the sum of the first and last digits?

To find the product of the given number and its reverse, we have 7146 * 6417 = 45860142. Rounding this to the nearest whole number gives 45860142 rounded to 45860142. The middle two digits of 7146 are 1 and 4, so their product is 1 * 4 = 4. The sum of the first and last digits of 7146 is 7 + 6 = 13. Now, subtracting the sum of the first and last digits from the product of the middle two digits gives 4 - 13 = -9. Dividing the rounded product by -9 results in -45860142 / -9 = 5095571.77778. Rounding this number to the nearest whole number gives 5095572. So, the answer is 5095572. Finally, the sum of the digits in 5095572 is 5 + 0 + 9 + 5 + 5 + 7 + 2 = 33. Thus, the sum of the digits when the number 7146 is multiplied by its own reverse and then divided by the product of the middle two digits subtracted by the sum of the first and last digits is 33.

Question: What is the smallest positive integer multiple of 7146 that is also a perfect square?

To find the smallest positive integer multiple of 7146 that is a perfect square, we need to find the square root of 7146 and find the smallest integer multiple of 7146 that is not less than the square root, then square that multiple. The square root of 7146 is approximately 84.59. The smallest integer multiple of 7146 that is not less than 84.59 is 7146 itself. So, the smallest positive integer multiple of 7146 that is also a perfect square is 7146 squared, which equals 51,001,316.
