To express each of the given fractions with rational denominators, we will use the technique of rationalization. This involves multiplying the numerator and the denominator by the conjugate of the denominator. ### Solution: **(i)** For the expression \( \frac{1}{3 + \sqrt{2}} \): 1. **Identify the conjugate**: The conjugate of \( 3 + \sqrt{2} \) is \( 3 - \sqrt{2} \). 2. **Multiply numerator and denominator by the conjugate**: ...
