Step-by-step Solution
To compare the values of \( \sqrt[4]{2} \), \( \sqrt[5]{2} \), and \( \sqrt[3]{2} \), we can express each of these roots as powers of 2:
1. \( \sqrt[4]{2} = 2^{1/4} \)
2. \( \sqrt[5]{2} = 2^{1/5} \)
3. \( \sqrt[3]{2} = 2^{1/3} \)
Next, we can compare the exponents \( \frac{1}{4} \), \( \frac{1}{5} \), and \( \frac{1}{3} \). To do this, we can find a common denominator, which is 60:
- \( \frac{1}{4} = \frac{15}{60} \)
- \( \frac{1}{5} = \frac{12}{60} \)
- \( \frac{1}{3} = \frac{20}{60} \)
Now we can compare the fractions:
- \( \frac{15}{60} > \frac{12}{60} \) (so \( \sqrt[4]{2} > \sqrt[5]{2} \))
- \( \frac{20}{60} > \frac{15}{60} \) (so \( \sqrt[3]{2} > \sqrt[4]{2} \))
- \( \frac{20}{60} > \frac{12}{60} \) (so \( \sqrt[3]{2} > \sqrt[5]{2} \))
From these comparisons, we can conclude:
\[
\sqrt[3]{2} > \sqrt[4]{2} > \sqrt[5]{2}
\]
Thus, the order from largest to smallest is:
\[
\sqrt[3]{2}, \sqrt[4]{2}, \sqrt[5]{2}
\]
Quick Answer
The order from largest to smallest is \( \sqrt[3]{2}, \sqrt[4]{2}, \sqrt[5]{2} \).
