The correct Answer is:
To determine whether the statement "The square of a prime number is prime" is true or false, let's analyze it step by step. ### Step 1: Understand what a prime number is. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. For example, the first few prime numbers are 2, 3, 5, 7, 11, etc. **Hint:** Remember that a prime number can only be divided evenly by 1 and itself. ### Step 2: Find the square of a prime number. The square of a number is obtained by multiplying the number by itself. For example: - The square of 2 (which is prime) is \(2 \times 2 = 4\). - The square of 3 (which is prime) is \(3 \times 3 = 9\). - The square of 5 (which is prime) is \(5 \times 5 = 25\). **Hint:** To find the square of a number, just multiply it by itself. ### Step 3: Check if the squares are prime. Now, let's check if the squares we calculated are prime: - 4 is not a prime number (it can be divided by 1, 2, and 4). - 9 is not a prime number (it can be divided by 1, 3, and 9). - 25 is not a prime number (it can be divided by 1, 5, and 25). **Hint:** A number is prime only if it has exactly two distinct positive divisors: 1 and itself. ### Step 4: Conclusion. Since the squares of the prime numbers we examined (2, 3, and 5) are not prime, we conclude that the statement "The square of a prime number is prime" is false. **Final Answer:** (F)
