To solve the problem, we need to find \( n \) such that the ratio of the fifth term from the beginning to the fifth term from the end in the expansion of \( \left( \sqrt[4]{2} + \frac{1}{\sqrt[4]{3}} \right)^n \) is \( \sqrt{6} : 1 \). ### Step-by-Step Solution: 1. **Identify the terms**: Let \( A = \sqrt[4]{2} \) and \( B = \frac{1}{\sqrt[4]{3}} \). We need to find the fifth term from the beginning and the fifth term from the end in the expansion of \( (A + B)^n \). 2. **General Term**: ...
