1. Problem Description

The problem asks to find the value of the expression 61291421614\frac{6^{\frac{1}{2}}9^{\frac{1}{4}}}{216^{\frac{1}{4}}}.

2. Solution Steps

First, we express each number in terms of its prime factors:
6=236 = 2 \cdot 3
9=329 = 3^2
216=63=(23)3=2333216 = 6^3 = (2 \cdot 3)^3 = 2^3 \cdot 3^3
Now, substitute these into the given expression:
61291421614=(23)12(32)14(2333)14\frac{6^{\frac{1}{2}}9^{\frac{1}{4}}}{216^{\frac{1}{4}}} = \frac{(2 \cdot 3)^{\frac{1}{2}} (3^2)^{\frac{1}{4}}}{(2^3 \cdot 3^3)^{\frac{1}{4}}}
Using the power of a product rule (ab)n=anbn(ab)^n = a^n b^n and the power of a power rule (am)n=amn(a^m)^n = a^{mn}, we get:
212312324234334=212312312234334\frac{2^{\frac{1}{2}} \cdot 3^{\frac{1}{2}} \cdot 3^{\frac{2}{4}}}{2^{\frac{3}{4}} \cdot 3^{\frac{3}{4}}} = \frac{2^{\frac{1}{2}} \cdot 3^{\frac{1}{2}} \cdot 3^{\frac{1}{2}}}{2^{\frac{3}{4}} \cdot 3^{\frac{3}{4}}}
Now, we simplify the expression by combining the terms with the same base using the rule aman=amn\frac{a^m}{a^n} = a^{m-n}:
21234312+1234=2243434434=2143142^{\frac{1}{2} - \frac{3}{4}} \cdot 3^{\frac{1}{2} + \frac{1}{2} - \frac{3}{4}} = 2^{\frac{2}{4} - \frac{3}{4}} \cdot 3^{\frac{4}{4} - \frac{3}{4}} = 2^{-\frac{1}{4}} \cdot 3^{\frac{1}{4}}
Rewriting this using the property an=1ana^{-n} = \frac{1}{a^n}, we have:
314214=(32)14\frac{3^{\frac{1}{4}}}{2^{\frac{1}{4}}} = (\frac{3}{2})^{\frac{1}{4}}

3. Final Answer

(32)14(\frac{3}{2})^{\frac{1}{4}}
