Math question: How many different four-digit numbers can be formed using the digits 0, 1, 8, and 8, if repetition is allowed?

To find the number of different four-digit numbers that can be formed using the digits 0, 1, 8, and 8 with repetition allowed, we consider the possibilities for each digit position. In the thousands place, we have four options (0, 1, 8, or 8). In the hundreds, tens, and units places, we also have four options for each. Therefore, by the multiplication principle, the total number of different four-digit numbers is obtained by multiplying the number of options for each position: 4 × 4 × 4 × 4 = 256. Thus, there are 256 different four-digit numbers that can be formed using the digits 0, 1, 8, and 8 with repetition allowed.

Math question: What is the sum of the digits in the number 8108?

To find the sum of the digits in the number 8108, we will break it down into its four digit parts. The first digit is 8, the second digit is 1, the third digit is 0, and the fourth digit is 8. Now, to find the sum, we add these digits together: 8 + 1 + 0 + 8 = 17. Therefore, the sum of the digits in the number 8108 is 17.

Question: What is the largest three-digit prime factor of the number formed by repeating the digits of 8108 six times?

To find the number formed by repeating the digits of 8108 six times, we concatenate the digits: 81088108810881088108810881088. To determine the largest three-digit prime factor, we need to evaluate this number. Observing that the last two digits are divisible by 4, we conclude that the number is divisible by 8. Dividing it by 8, we get 1013601350135010136010135. Further, noticing that the sum of its digits is 27 (a multiple of 3), we conclude it must be divisible by 3. Therefore, dividing it by 3 gives 3378671167111673378671167. Finally, we realize that this number repeats every four digits. So let's focus on the first four digits (3378). Observing that 3378 = 2 × 1689, we conclude that the number is divisible by 2. Thus, dividing by 2 gives 168983983398339183983339183. At this point, we see that the number repeats every three digits. Now we focus on the first three digits (168). By evaluating the factors of 168, we can notice that 168 = 2 × 2 × 2 × 3 × 7. However, since we're looking for the largest three-digit prime factor, the largest prime factor of 168 is 7. So, the largest three-digit prime factor of the number 81088108810881088108810881088 is 7.
