Simplifying 5644\sqrt[4]{\frac{5}{64}}

To simplify the expression 5644\sqrt[4]{\frac{5}{64}}, first rewrite it using the Quotient Property as 54644\frac{\sqrt[4]{5}}{\sqrt[4]{64}}. Before rationalizing, simplify the denominator by factoring the radicand: 644=264=2224\sqrt[4]{64} = \sqrt[4]{2^6} = 2\sqrt[4]{2^2}. The expression becomes 542224\frac{\sqrt[4]{5}}{2\sqrt[4]{2^2}}. Next, rationalize the denominator by multiplying both the numerator and the denominator by 224\sqrt[4]{2^2} to complete the perfect fourth power, providing 4 total factors of 2. This yields 542242224224=2042244\frac{\sqrt[4]{5} \cdot \sqrt[4]{2^2}}{2\sqrt[4]{2^2} \cdot \sqrt[4]{2^2}} = \frac{\sqrt[4]{20}}{2\sqrt[4]{2^4}}. Since 244=2\sqrt[4]{2^4} = 2, the denominator simplifies to 4. The final result is 2044\frac{\sqrt[4]{20}}{4}.
