All square numbers have an odd numberof factors. A prime number by definition has exactly 2 factors - 1 and itself.
The number of days Christen's book is overdue could be 22 according to options given.
The graph which represents the relationship between the number of days a book is overdue and the library fine charged is attached below :
According to the graph, a constant relationship exists between the number of days a book is overdue and the library fine charged when the Number of days book is overdue is about 19 days and above such that the library fine charged stays the same at $10.
Since we are told that Christen's fine for returning the book is the same as the fine she would have paid if book was returned yesterday, then, the number of days Christen's book is overdue could be 20 days and above.
The only value above 20 from the options given is 22.
Hence, 22 is the valid answer.
Considering the conversion from exponent to radical, the equation that justifies why the expression
is correct is.

<h3>How is the conversion from exponent to radical realized?</h3>
The conversion of rational exponents to radical notation is modeled by:
![a^{\frac{n}{m}} = \sqrt[m]{a^n}](https://tex.z-dn.net/?f=a%5E%7B%5Cfrac%7Bn%7D%7Bm%7D%7D%20%3D%20%5Csqrt%5Bm%5D%7Ba%5En%7D)
In this problem, the expression is:
![9^{\frac{1}{3}} = \sqrt[3]{9}](https://tex.z-dn.net/?f=9%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%20%3D%20%5Csqrt%5B3%5D%7B9%7D)
And the equation that shows that this is correct is:
