Answer:
1st option - [tex]\frac{1}{\sqrt[5]{7x } }[/tex]
Step-by-step explanation:
A fractional power can be broken down.
The denominator will be the root number
The numerator will be the power
For example x^1/2 = √x^1 = √x
So :
[tex]\frac{1}{7x^{\frac{1}{5} } }[/tex] = [tex]\frac{1}{\sqrt[5]{7x^{2} } }[/tex] = [tex]\frac{1}{\sqrt[5]{7x}}[/tex]
So 1st option
