Math question: If the number 393 is divided by 3, multiplied by 7, and then subtracted by 99, what is the result?

To find the result, we first divide 393 by 3, which equals 131. Next, we multiply 131 by 7 to get 917. Finally, we subtract 99 from 917, resulting in 818. Therefore, after the operations, the final result is 818.

Math Question: Let's say we have the number 393. What is the product of its digits multiplied together? Explanation of the Question: To solve this question, we need to break down the number 393 into its digits. The digits of 393 are 3, 9, and 3. We then multiply these three digits together as mentioned in the question.

The product of multiplying these digits together is obtained by performing 3 x 9 x 3 = 81.

Math question: What is the cube root of 393?

The cube root of a number is the value that, when multiplied by itself twice, gives the original number. To find the cube root of 393, we need to find a number that satisfies this condition. Using trial and error, we can calculate: - If we try 7 as the cube root, 7^3 = 343, which is less than 393. - If we try 8 as the cube root, 8^3 = 512, which is greater than 393. - Hence, the cube root of 393 lies between 7 and 8. Now, to approximate it further, we can use a numerical method like the Newton-Raphson iteration: - Let's assume the cube root lies between 7 and 8 and begin with our initial approximation of 7.5. - Using the Newton-Raphson iteration formula: x1 = x0 - f(x0)/f'(x0), we can iteratively improve our approximation. - The derivative of the cube root function is 1/3 * 393^(-2/3). - After several iterations, we find that the cube root of 393 is approximately 7.3703. In conclusion, the approximate cube root of 393 is 7.3703.
