Question: What is the sum of the digits in the number 7977 when each digit is raised to the power of its place value and added together?

To find the sum of the digits, we raise each digit to the power of its place value. The number 7977 can be written as 7^3 + 9^2 + 7^1 + 7^0. Calculating, we get 343 + 81 + 7 + 1 = 432. Therefore, the sum of the digits in 7977, when each digit is raised to the power of its place value and added together, is 432.

Math Question: What is the largest prime factor of the number 7977?

To find the largest prime factor of 7977, we first observe that it is an odd number. We divide it by the smallest prime number, 3, to get 2659 as the quotient. Now, let's check if it is divisible by any primes up to the square root of 2659, which is approximately 51.6. By testing from 3 to 51, we find that 7 is the largest prime that divides evenly into 2659. Therefore, the largest prime factor of 7977 is 7.

Math question: What is the sum of the ones, tens, hundreds, and thousands digits of the number 7977?

To find the sum of the digits, we separate the number 7977 into its individual digits: 7, 9, 7, and 7. Then, we add these digits together: 7 + 9 + 7 + 7 = 30. Therefore, the sum of the ones, tens, hundreds, and thousands digits of the number 7977 is 30.
