Math question: What is the sum of twice the square root of 866 and three times the cube root of 866, rounded to the nearest whole number?

To solve this, let's calculate each component separately. First, find the square root of 866, which is approximately 29.41. Doubling this gives us 58.82. Then, find the cube root of 866, which is roughly 9.09. Multiplying this by three yields 27.27. Adding these values together gives a sum of approximately 86.09. Rounding this to the nearest whole number, we obtain 86 as the final answer.

Math question: If a number is multiplied by 866 and the product is divided by 2, then the result is subtracted by 100, what is the final value?

To find the final value, we perform the following steps: Multiply the number by 866, then divide the product by 2, and finally subtract 100 from the result. Let's denote the number as 'x'. The expression to calculate the final value is ((866 * x) / 2) - 100. For example, let's assume we have x = 10. Plugging this into the equation, we get ((866 * 10) / 2) - 100 = (8660 / 2) - 100 = 4330 - 100 = 4230. Hence, the final value is 4230. In general, for any value of 'x', following the above steps will lead to an expression that evaluates to the final value of the given number after undergoing multiplication, division, and subtraction.

What is the square of the number formed by reversing the digits of 866?

To find the square of 866, we first reverse its digits to get 668. Now, we square 668 to determine the answer. 668 * 668 = 445,024. So, the square of the number formed by reversing the digits of 866 is 445,024.
