Math question: If 8449 is a perfect square, what is the closest perfect square below it?

To determine the closest perfect square below 8449, we can take the square root of 8449, which is approximately 91.861. Since the closest perfect square below 91.861 is 81, the closest perfect square below 8449 is 81* 81 = 6561.

Math question: What is the sum of the digits in the number 8449 squared, divided by the square root of 8449?

To find the sum of the digits, we calculate 8 + 4 + 4 + 9 = 25. Squaring 8449 gives us 713,488,801. Taking the square root of 8449 gives approximately 91.9. Dividing the square of the sum of digits (713,488,801) by the square root of 8449 (91.9), we get an answer of approximately 7,757,545.77 (rounded to two decimal places).

Math Question: What is the value of 8449 when rounded to the nearest hundred?

To round 8449 to the nearest hundred, we identify the hundreds digit which is 4. The tens digit after it is 4, which is less than 5. Thus, the hundreds digit remains the same, and the remainder (tens and ones digit) becomes zero. Therefore, when rounding 8449 to the nearest hundred, the result is 8400. Rounding is a technique used to approximate a number to a specified place value. In this case, rounding 8449 to the nearest hundred aims to simplify the number while maintaining its proximity to the original value.
