Answer:
B
Step-by-step explanation:
[tex]5^{-1/7}[/tex]
= [tex]\frac{1}{5^{1/7} }[/tex]
= 1 / [tex]\sqrt[7]{5}[/tex]
Answer:
Option B
Step-by-step explanation:
To remove a negative power we put the number under one :
[tex]5^{-\frac{1}{7} } = \frac{1}{5^{\frac{1}{7} } }[/tex]
To remove the fractional power we make the denominator the root and the numerator the power:
[tex]\frac{1}{5^{\frac{1}{7} } } = \frac{1}{\sqrt[7]{5^{1} } } = \frac{1}{\sqrt[7]5}[/tex]
Therefore [tex]\frac{1}{\sqrt[7]5}[/tex] - Option B is our final answer
