# Algebraic Expressions and Rationalizations

## Problem Set

### Problem 1:
**Simplify the expression:**  
\((125x^{\frac{1}{2}}y^6)^{\frac{1}{3}}\)

- **Options:**
  - A: \(\frac{125}{3}y^{\frac{6}{3}}\sqrt{x}\)
  - B: \(5y^2\sqrt[3]{x}\)
  - C: \(5x^{\frac{5}{6}}y\)
  - D: **None of these**

### Problem 8:
**Evaluate the rational expression:**  
\(\frac{6x^2 - 11x + 4}{2x^2 + 5x - 3}\)

- **Options:**
  - A: \(\frac{3x - 4}{x + 3}\)
  - B: \(\frac{(6x - 1)(x - 4)}{(2x + 3)(x - 1)}\)
  - C: \(3x^2 - \frac{11}{5}x - \frac{4}{3}\)
  - D: **None of these**

### Problem 9:
**Solve the expression:**  
\(\frac{x^2 - y^2}{2x + y} \cdot \frac{4x + 2xy}{y - x}\)

- **Options:**
  - A: \(2x + y\)
  - B: \(-2x(x + y)\)
  - C: \(\frac{2x(x + y)}{y - x}\)
  - D: **None of these**

### Problem 10:
**Rationalize the denominator:**  
\(\frac{4 - 3\sqrt{2}}{6 + \sqrt{2}}\)

- **Options:**
  - A: \(\frac{15 - 11\sqrt{2}}{17}\)
  - B: \(\frac{9 - 7\sqrt{2}}{19}\)
  - C: \(-\frac{1}{4}\)
  - D: **None of these**

### Problem 11:
**Evaluate the expression:**  
\(\frac{2a^2 - ab - b^2}{6x^2 - x
