Answer:
$4.67
Step-by-step explanation:
First, add the price with the sales tax:
19(1.07)
= 20.33
To find how much she got back in change, subtract 20.33 from 25
25 - 20.33
= 4.67
So, she got $4.67 in change
Remember, the numerator of an exponenent represents the root. As well, a negative exponent means to take the reciprocal of the positive exponent (
.
So, 
is equal to ![\sqrt[3]{64^{-1}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B64%5E%7B-1%7D%7D)
which is 1/4, because 1/4*1/4*1/4 is 1/64 (1/64 cubed root is 1/4).
For example, ![a^{b/c} = \sqrt[c]{b^{b}}](https://tex.z-dn.net/?f=a%5E%7Bb%2Fc%7D%20%3D%20%5Csqrt%5Bc%5D%7Bb%5E%7Bb%7D%7D)
The answer is c.
