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}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D%3Da%5E%5Cfrac%7B1%7D%7Bn%7D%5CRightarrow%5Csqrt%5B5%5D%7Bx%7D%3Dx%5E%5Cfrac%7B1%7D%7B5%7D%5C%5C%5C%5C%5Csqrt%5B5%5D%7Bx%7D%5Ccdot%5Csqrt%5B5%5D%7Bx%7D%5Ccdot%5Csqrt%5B5%5D%7Bx%7D%5Ccdot%5Csqrt%5B5%5D%7Bx%7D%3Dx%5E%5Cfrac%7B1%7D%7B5%7D%5Ccdot%20x%5E%5Cfrac%7B1%7D%7B5%7D%5Ccdot%20x%5E%5Cfrac%7B1%7D%7B5%7D%5Ccdot%20x%5E%5Cfrac%7B1%7D%7B5%7D%5Cqquad%5Ctext%7Buse%7D%5C%20a%5En%5Ccdot%20a%5Em%3Da%5E%7Bn%2Bm%7D%5C%5C%5C%5C%3Dx%5E%7B%5Cfrac%7B1%7D%7B5%7D%2B%5Cfrac%7B1%7D%7B5%7D%2B%5Cfrac%7B1%7D%7B5%7D%2B%5Cfrac%7B1%7D%7B5%7D%7D%3Dx%5E%5Cfrac%7B4%7D%7B5%7D)
Answer:

Step-by-step explanation:
fifth root of x can be written in exponential for as:

times
times
times 
WE apply exponential property to multiply it
a^m times a^n= a^{m+n}
times
times
times 

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