Math Question: What is the largest prime factor of the number 258?

To find the largest prime factor of 258, we'll begin by factoring it. Dividing 258 by prime numbers, we get: 2 × 129. Continuing the process with 129, we find it to be divisible by 3: 3 × 43. Finally, 43 is a prime number. Therefore, the largest prime factor of 258 is 43.

Question: What is 258 divided by the product of the square root of 10 and the cube root of 2, multiplied by the sum of 5 and the fourth root of 16, all subtracted by the quotient of 258 and the natural logarithm of 10?

To solve this complex equation, let's break it down. The square root of 10 is approximately 3.1623, and the cube root of 2 is approximately 1.2599. The fourth root of 16 is 2, and the natural logarithm of 10 is approximately 2.3026. Now, we have 258 divided by (3.1623 × 1.2599) × (5 + 2) - (258 ÷ 2.3026). Simplifying further, we get 258 ÷ (3.9841 × 7) - 112.0292. Thus, the final answer is approximately -106.16.

Math Question: If you multiply a number by 3, subtract 10, divide by 2, and then add 20, the result is 258. What is the original number?

Let's represent the unknown number as x. According to the given information, we can form the equation: ((3x - 10) ÷ 2) + 20 = 258. To solve, we'll start by simplifying the equation. First, multiply (3x - 10) ÷ 2 by 2 to get 3x - 10 + 40 = 516. Combining like terms, we have 3x + 30 = 516. Next, subtracting 30 from both sides yields 3x = 486. Finally, dividing both sides by 3 gives x = 162. Therefore, the original number is 162.
