these are the answer choices
\[\sqrt{x} \]

\[x \sqrt[5]{x^3}\]
\[x^{16/25}\]
and Yeah i know what you meant lol typos happen
OpenStudy (anonymous):
so x = 20

start by writing each term in index form
\[\sqrt[5]{x^4} = x^{\frac{4}{5}}\]
the the rule for multiplying the same base is add the powers
\[a^y \times a^z = a^{y + z}\]
now apply the rule to your problem
OpenStudy (anonymous):
thnx to both of you!

np
