The correct Answer is:
To analyze the statements provided, we will evaluate each statement step by step. ### Step 1: Analyze Statement 1 **Statement 1:** For \( n \in \mathbb{N}, n > 1, \, 2^n > n^{(n-1)/2} \) 1. **Identify the natural numbers greater than 1:** The natural numbers greater than 1 are \( n = 2, 3, 4, \ldots \). 2. **Check the inequality for various values of \( n \):** - For \( n = 2 \): \[ 2^2 = 4 \quad \text{and} \quad 2^{(2-1)/2} = 2^{1/2} = \sqrt{2} \approx 1.41 \] Thus, \( 4 > 1.41 \) is true. - For \( n = 3 \): \[ 2^3 = 8 \quad \text{and} \quad 3^{(3-1)/2} = 3^{1} = 3 \] Thus, \( 8 > 3 \) is true. - For \( n = 4 \): \[ 2^4 = 16 \quad \text{and} \quad 4^{(4-1)/2} = 4^{3/2} = 8 \] Thus, \( 16 > 8 \) is true. - For \( n = 5 \): \[ 2^5 = 32 \quad \text{and} \quad 5^{(5-1)/2} = 5^{2} = 25 \] Thus, \( 32 > 25 \) is true. - For \( n = 6 \): \[ 2^6 = 64 \quad \text{and} \quad 6^{(6-1)/2} = 6^{5/2} = 6 \cdot \sqrt{6} \approx 14.7 \] Thus, \( 64 > 14.7 \) is true. We can observe that for \( n = 2, 3, 4, 5, 6 \), the inequality holds true. 3. **Conclusion for Statement 1:** The statement appears to be true for natural numbers greater than 1 based on the values checked. ### Step 2: Analyze Statement 2 **Statement 2:** The Arithmetic Mean (A.M.) of distinct positive numbers is greater than the Geometric Mean (G.M.). 1. **Define A.M. and G.M.:** - For two distinct positive numbers \( a \) and \( b \): \[ \text{A.M.} = \frac{a + b}{2} \] \[ \text{G.M.} = \sqrt{ab} \] 2. **Apply the Arithmetic Mean-Geometric Mean Inequality:** - According to the A.M.-G.M. inequality: \[ \frac{a + b}{2} \geq \sqrt{ab} \] - The equality holds when \( a = b \). Since we are considering distinct positive numbers, we have: \[ \frac{a + b}{2} > \sqrt{ab} \] 3. **Conclusion for Statement 2:** This statement is true for any two distinct positive numbers. ### Final Conclusion - **Statement 1:** True - **Statement 2:** True
