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**: The expression can be rewritten as \( \left( 2\sqrt{4} + \frac{1}{\sqrt{4}3} \right)^n \). Here, \( x = 2\sqrt{4} = 4 \) and \( y = \frac{1}{\sqrt{4}3} = \frac{1}{6} \). ...
