Question

question
express $8^{\frac{1}{5}}$ in simplest radical form.
answer attempt 4 out of 4

Explanation:

Step1: Recall the exponent rule \( a^{\frac{m}{n}}=\sqrt[n]{a^m} \) (when \( n>0 \)). For \( 8^{\frac{1}{5}} \), here \( a = 8 \), \( m = 1 \), \( n = 5 \).

So by the rule, \( 8^{\frac{1}{5}}=\sqrt[5]{8^1} \)

Step2: Simplify \( 8^1 \) which is just 8. So we have \( \sqrt[5]{8} \). Since 8 cannot be simplified further under a fifth - root (as 8 does not have any perfect fifth - power factors other than 1), this is the simplest radical form.

Answer:

\(\sqrt[5]{8}\)
