Math Question: How many prime numbers can be formed by rearranging the digits of the number 9879?

To determine the number of prime numbers that can be derived by rearranging the digits of 9879, we can use the divisibility rule for 3. Prime numbers greater than 3 cannot have their digits sum to a multiple of 3. The original number, 9879, has its sum of digits equal to 33, which is a multiple of 3. Therefore, any rearrangement of the digits of 9879 will also have a sum of digits equal to 33 and will be divisible by 3. Since prime numbers are not divisible by any other number except 1 and itself, no rearrangement of the digits of 9879 can be prime. Hence, the answer is that no prime numbers can be formed by rearranging the digits of 9879.

Math Question: If the number 9879 is multiplied by 4 and divided by 3, what is the result when 5432 is subtracted? Math

To solve the problem, we start by multiplying 9879 by 4, which gives us 39516. When we divide 39516 by 3, the result is 13172. Now, if we subtract 5432 from 13172, we get 7740. Therefore, the final answer is 7740.

Math question: How many prime numbers are there between 9879 and 9879 + 200?

To find the number of prime numbers between 9879 and 10079, we need to check if each number within this range is divisible by any numbers other than 1 and itself. By applying the divisibility rule, we can determine whether each number in the range is prime or composite. This process requires checking divisibility by prime numbers up to the square root of the given number. Counting the prime numbers within this range will provide us with the answer.
