The correct Answer is:
To determine whether the statement "The product of two even numbers is always even" is true or false, we can follow these steps: ### Step 1: Understand what even numbers are Even numbers are integers that are divisible by 2 without leaving a remainder. This means that when you divide an even number by 2, the result is a whole number. **Hint:** Remember that even numbers can be expressed in the form of 2n, where n is any integer. ### Step 2: Write the expression for the product of two even numbers Let’s denote two even numbers as 2a and 2b, where a and b are integers. The product of these two even numbers can be expressed as: \[ (2a) \times (2b) \] **Hint:** Think about how you can represent any even number mathematically. ### Step 3: Calculate the product Now, let's calculate the product: \[ (2a) \times (2b) = 4ab \] **Hint:** Notice that 4ab can be factored to show that it is still divisible by 2. ### Step 4: Determine if the product is even Since 4ab is a multiple of 2 (specifically, it is 2 times 2ab), we can conclude that the product is even. **Hint:** Check if the result of your multiplication can be divided by 2 without a remainder. ### Step 5: Provide examples To further confirm, we can take specific examples of even numbers: - Example 1: 2 and 4 \[ 2 \times 4 = 8 \quad (\text{even}) \] - Example 2: 6 and 12 \[ 6 \times 12 = 72 \quad (\text{even}) \] **Hint:** Using specific numbers can help solidify your understanding of the concept. ### Conclusion Since we have shown that the product of two even numbers is always even through both algebraic reasoning and specific examples, we can confidently state that the statement is **True**. **Final Answer:** True
