Math question: What is the sum of the digits in the number 783?

To find the sum of the digits, we break down the number 783 into its individual digits: 7, 8, and 3. To calculate the sum, we add these digits together: 7 + 8 + 3 = 18. So, the sum of the digits in the number 783 is 18.

Math question: If 783 is divided by 9 and then multiplied by 7, what is the result?

To calculate the result, divide 783 by 9, which gives 87 as the quotient. Then, multiply this quotient by 7 to find the desired result. This yields 609. Therefore, when 783 is divided by 9 and then multiplied by 7, the result is 609.

Question: What is the square root of 783 rounded to two decimal places?

The square root of 783 is approximately 27.97. To find this, we can use methods like prime factorization or Newton's method. Start by factoring 783 into its prime factorization: 3^2 × 7 × 37. By grouping the prime factors, we have (3 × 3) × (7 × 37), which simplifies to 9 × 259. Taking the square root, we get √(9 × 259) = √(9) × √(259) = 3 × √(259). Now, to estimate √(259), we can try √(256) = 16, which is too small, and √(289) = 17, which is too large. Therefore, we can deduce that √(259) is slightly less than 17. By substituting into 3 × √(259), we have 3 × (slightly less than 17), resulting in the square root of 783 being approximately 27.97.
