Math Question: What is the square root of the sum of the number 745 multiplied by the cube root of 745?

To find the solution, we first calculate the sum of 745, which is 745 itself. Then, we calculate the cube root of 745, which is approximately 9.91. We multiply the sum of 745 by the cube root of 745, giving us 745 * 9.91 ≈ 7379.95. Finally, we take the square root of this value, resulting in √(745 * 9.91) ≈ √7379.95. Hence, the answer is approximately 86. Among the possible variations, this specific math question tests knowledge of square roots, multiplication, addition, and cube roots in a concise manner.

Math question: If you subtract 149 from a number and then multiply it by 5, the result is 3725. What is the number?

Let's assume the number be x. According to the given condition, (x - 149) * 5 = 3725. Distributing the multiplication and simplifying the equation, we get 5x - 745 = 3725. Adding 745 to both sides, we have 5x = 4470. Finally, dividing both sides by 5, we find x = 894. Therefore, the number is 894.

Math question: What is the sum of the digits in the number 745?

The sum of the digits in the number 745 can be found by adding 7 + 4 + 5, which equals 16.
