Answer:
![\sqrt[8]x = x^\frac{1}{6}](https://tex.z-dn.net/?f=%5Csqrt%5B8%5Dx%20%3D%20x%5E%5Cfrac%7B1%7D%7B6%7D)
Step-by-step explanation:
Given:
![\sqrt[6] x](https://tex.z-dn.net/?f=%5Csqrt%5B6%5D%20x)
Required
Represent as an exponent
In indices, we have:
![\sqrt[n]x = x^\frac{1}{n}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5Dx%20%3D%20x%5E%5Cfrac%7B1%7D%7Bn%7D)
By comparison:
![\sqrt[8]x = \sqrt[n]x](https://tex.z-dn.net/?f=%5Csqrt%5B8%5Dx%20%3D%20%5Csqrt%5Bn%5Dx)

Apply this law to the given expression:
We have:
![\sqrt[8]x = x^\frac{1}{6}](https://tex.z-dn.net/?f=%5Csqrt%5B8%5Dx%20%3D%20x%5E%5Cfrac%7B1%7D%7B6%7D)
Answer:
106 degrees
Step-by-step explanation:
Here are the steps to solving:
1) Write out problem 3.6+7.2k <25.2
2) Subtract 3.6 7.2k <21.6
3) Divide by 7.2 k <3
So k<3 would be your answer
