The "primer" of 10 is also equal to the primer of E. 12.
The primer of a number is defined as the sum of all of its distinct prime factors. To find the primer of a number, we first need to determine its prime factors and then sum them up. For example, the prime factors of 10 are 2 and 5, so the primer of 10 is 2 + 5 = 7.
Now, let's consider the primer of E. 12. To find the primer of 12, we need to find its prime factors, which are 2 and 3, and then add them together: 2 + 3 = 5.
Comparing the primer of 10 (7) with the primer of 12 (5), we can see that they are equal. Therefore, the answer is E. 12.
Step-by-step explanation:
The primer of a number is a mathematical concept that involves finding the sum of all its distinct prime factors. To calculate the primer, we first identify the prime factors of the given number, which are the prime numbers that can divide the number without leaving any remainder. Once we have the prime factors, we simply add them together to get the primer value.
For instance, let's take the number 10. The prime factors of 10 are 2 and 5 because 10 can be expressed as 2 x 5. So, the primer of 10 is the sum of its prime factors, which is 2 + 5 = 7.
Now, we need to find the primer of E. 12. Since the options provided are all integers, it's important to realize that "E. 12" stands for option E, which is the number 12. The prime factors of 12 are 2 and 3 (because 12 = 2 x 2 x 3). Hence, the primer of 12 is 2 + 3 = 5.
Comparing the primer of 10 (7) with the primer of 12 (5), it is evident that they are equal. Thus, the primer of 10 is also equal to the primer of 12, making option E. 12 the correct answer.
