Remove the negative exponent.

If n<span> is a positive </span>integer<span> that is greater than </span>x<span> and </span>a<span> is a real number or a </span>factor, then
![a \frac{x}{n} = \sqrt[n]{a ^{x} }](https://tex.z-dn.net/?f=a%20%5Cfrac%7Bx%7D%7Bn%7D%20%3D%20%5Csqrt%5Bn%5D%7Ba%20%5E%7Bx%7D%20%7D%20)
<span>Use the rule to convert (5x)</span>

to a radical, where a= 5x, x=5, and n=4.
so the answer would be..
![\frac{1}{ \sqrt[4]{(5x) ^{5} } }](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B%20%5Csqrt%5B4%5D%7B%285x%29%20%5E%7B5%7D%20%7D%20%7D%20)
hope this helped and sorry if it was kind of confusing.
Using proportions, it is found that her discount is of $0.29664.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount.
In this problem, the total amount she spent on gas is given by:
T = $45.23 + $102.34 + $13.67 + $34.56 + $48.72 + $52.12 = $296.64.
Considering that she receives ten cents off per gallon on gas for every $100 she spends, we apply the <em>proportion </em>to find that her discount is given by:

Her discount is of $0.29664.
