Answer:
A natural number greater than 1 that has only itself and 1 as factors is called a prime number
Step-by-step explanation:
- A prime number is a natural number greater than 1, that has only two factors;- the natural number itself and 1.
- Example:
- The factors of 13 are {1,13}, therefore 13 is a prime number.
- The factors of 2 are {1.2}, therefore 2 is also a prime number.
- Composite numbers have two or more factors.
- An exponential number is a power of natural numbers. An example is [tex]9=3^2[/tex]
- The first choice is correct
