subtract 10 on both sides of the equal sign
c = -7
Answer:

Step-by-step explanation:
Answer:
1,215 Superscript one-fifth x
Step-by-step explanation:
Given:
The expression to simplify is given as:
![(\sqrt[5]{1215})^x](https://tex.z-dn.net/?f=%28%5Csqrt%5B5%5D%7B1215%7D%29%5Ex)
We know that,
![\sqrt[n]{a} = a^{\frac{1}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D%20%3D%20a%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D)
Here, 
So, ![\sqrt[5]{1215} = 1215^{\frac{1}{5}}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B1215%7D%20%3D%201215%5E%7B%5Cfrac%7B1%7D%7B5%7D%7D)
So, the above expression becomes:
![(\sqrt[5]{1215})^x = (1215^{\frac{1}{5}})^x](https://tex.z-dn.net/?f=%28%5Csqrt%5B5%5D%7B1215%7D%29%5Ex%20%3D%20%281215%5E%7B%5Cfrac%7B1%7D%7B5%7D%7D%29%5Ex)
Now, using the law of indices 
Here, 
So, the expression is finally simplified to;
Therefore, the second option is the correct one.
= 1,215 Superscript one-fifth x
Answer:
number of shoes is independent, number of racks is dependent
Step-by-step explanation:
the number of racks does not affect the number of shoes but if there are a lot of shoes, the number of racks will increase.
