What is the sum of the digits in the number 2823?

To find the sum of the digits in the number 2823, we add each digit: 2 + 8 + 2 + 3 = 15.

What is the value of the expression 2 × (8 + 2) - 3 × 2^3 ÷ 2 - 3 + √2823 rounded to the nearest tenth?

To solve this expression, start by simplifying the inner parentheses 8 + 2 = 10. Next, calculate 2^3 = 8 and divide that by 2, resulting in 4. Multiply 3 by 4, resulting in 12. Subtracting 12 from 20 gives us 8. Finally, find the square root of 2823 ≈ 53.097 and round it to the nearest tenth ≈ 53.1. Adding all the values, we get 53.1 - 3 + 8 = 58.1. Thus, the answer is approximately 58.1.

Math question: What is the largest prime factor of the number 2823?

To find the largest prime factor of 2823, we start by factoring it. Since 2823 is an odd number, it cannot be divisible by 2. We try dividing by 3, and the result is 941. This means that 2823 = 3 × 941. Therefore, the largest prime factor of 2823 is 941, a prime number that cannot be further divided.
