Answer:

\large\boxed{x^\frac{4}{5}}

Step-by-step explanation:

\sqrt[n]{a}=a^\frac{1}{n}\Rightarrow\sqrt[5]{x}=x^\frac{1}{5}\\\\\sqrt[5]{x}\cdot\sqrt[5]{x}\cdot\sqrt[5]{x}\cdot\sqrt[5]{x}=x^\frac{1}{5}\cdot x^\frac{1}{5}\cdot x^\frac{1}{5}\cdot x^\frac{1}{5}\qquad\text{use}\ a^n\cdot a^m=a^{n+m}\\\\=x^{\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}}=x^\frac{4}{5}

Answer:

x^{\frac{4}{5}}

Step-by-step explanation:

fifth root of x can be written in exponential for as:

x^\frac{1}{5}

x^\frac{1}{5} times  x^\frac{1}{5} times  x^\frac{1}{5} times  x^\frac{1}{5}

WE apply exponential property to multiply it

a^m times a^n= a^{m+n}

x^\frac{1}{5} times  x^\frac{1}{5} times  x^\frac{1}{5} times  x^\frac{1}{5}

x^{\frac{1}{5} +\frac{1}{5}+\frac{1}{5}+\frac{1}{5}}

The denominator of the fractions are same so we add the numerators

x^{\frac{4}{5}}
