Math question: What is the smallest prime factor of the number 7965?

To find the prime factorization of 7965, we divide it by the smallest prime numbers starting from 2 (7965 ÷ 2 = 3982.5, not an integer). Continuing this process, we divide by 3 (7965 ÷ 3 = 2655, an integer), giving us the smallest prime factor, which is 3. Therefore, the smallest prime factor of 7965 is 3.

Math Question: What is the sum of the digits in the number 7965? Math

To find the sum of the digits in 7965, we need to add the individual digits together. Starting with the thousands digit, 7, we add it to the hundreds digit, 9, then the tens digit, 6, and finally the units digit, 5. Hence, 7 + 9 + 6 + 5 equals 27. Therefore, the sum of the digits in the number 7965 is 27.

Question: What is the sum of the digits in the number 7965 when each digit is raised to the power of its respective place value position, multiplied by its position in the number, and then squared?

To find the answer, we start by breaking down the number 7965 into its individual digits: 7, 9, 6, and 5. Then, we raise each digit to the power of its respective place value position: 7^3, 9^2, 6^1, and 5^0. Next, we multiply each power by the digit's position in the number: (7^3) * 1, (9^2) * 2, (6^1) * 3, and (5^0) * 4. Finally, we square each result: [(7^3) * 1]^2, [(9^2) * 2]^2, [(6^1) * 3]^2, and [(5^0) * 4]^2. Calculating these values gives us: 343^2, 162^2, 18^2, and 4^2. The sum of these squares is 118,049 + 26,244 + 324 + 16 = 144,633. Therefore, the answer is 144,633.
