Transcribed Image Text:### Problem 8:
**Objective:**
Prove \( n^3 > 2n^2 + 7n + 7 \) for every \( n \geq 10 \) by mathematical induction.
**Explanation:**
This problem requires the use of mathematical induction to demonstrate the inequality \( n^3 > 2n^2 + 7n + 7 \) for all integers \( n \) greater than or equal to 10.
**Steps for Mathematical Induction:**
1. **Base Case:** Verify the inequality for \( n = 10 \).
2. **Induction Hypothesis:** Assume the inequality holds for some arbitrary integer \( k \geq 10 \). That is, assume \( k^3 > 2k^2 + 7k + 7 \) is true.
3. **Inductive Step:** Use the induction hypothesis to show that \( (k+1)^3 > 2(k+1)^2 + 7(k+1) + 7 \).
By proving that if the inequality holds for \( n = k \), then it must also hold for \( n = k + 1 \), and by confirming the base case, we validate the inequality for all \( n \geq 10 \).
This method ensures the statement holds universally for the specified range of \( n \).
