Math question: What is the sum of 257 and its double, subtracted by half of its square, divided by the cube root of 257, and rounded to the nearest whole number?

To solve this, we start by finding the square of 257, which is 66049. Then, we find the double of 257, which is 514. Next, we subtract half of the square: 66049/2 = 33024.5. Adding 514 to this gives us 33538.5. Finally, we divide this by the cube root of 257, which is approximately 6.2308. Dividing 33538.5 by 6.2308, we get 5383.2096. Rounding to the nearest whole number, the answer is 5383.

Question: Find the product of the prime factors of the number 257?

To find the prime factors of 257, we start by checking for divisibility by prime numbers. Since 257 is not divisible by 2, 3, 5, or 7, we move to the next prime number, which is 11. Upon division, we find that 257 is not divisible by 11. Continuing this process with subsequent prime numbers, we finally find that 257 is divisible by 257 (which is a prime number itself). Hence, the prime factors of 257 are 257 itself. Therefore, the product of the prime factors of 257 is simply 257.

What is the result when you multiply 257 by 6, subtract 172, divide by 9, add 8, square the number, subtract 35, divide by 2, and multiply by 3?

The result of multiplying 257 by 6 is 1542. Subtracting 172 gives 1370. Dividing by 9 yields 152.22. Adding 8 results in 160.22. Squaring that gives 25677.9684. Subtracting 35 yields 25642.9684. Dividing by 2 gives 12821.4842. Multiplying by 3 results in 38464.4525.
