All we want to do is use the formula...
![x^{ \frac{a}{n} } = \sqrt[n]{a^x}](https://tex.z-dn.net/?f=%20x%5E%7B%20%5Cfrac%7Ba%7D%7Bn%7D%20%7D%20%3D%20%20%5Csqrt%5Bn%5D%7Ba%5Ex%7D%20)
In doing so we should get...
![\sqrt[5]{y}](https://tex.z-dn.net/?f=%20%5Csqrt%5B5%5D%7By%7D%20)
This is an equivalent expression however just the radical form of your given expression.

Answer: The worm slithers 48 inches in an hour. The snail slithers 52 inches in an hour.
If we start by making both the races into equations we get 5w+4s=448 inch and 2w+3s=252 inch. If we then add both the equations together we get 7w+7s=700 inch. Then we divide it all to get 1w+1s=100 inch. Then we can subtract the second race from the first to get 3w+1s=196 inch. We now know that 2w=96 inch, and can therefor divide whit 2 to find out w=48. We can then figure out how fast the snail is moving by multiplying 48 whit w and dividing the answer by s.

Answer:
-4x + y + 6z
Step-by-step explanation:
Combine like terms (Terms with the same variable):
(2x + 5y - z) + (-6x - 4y + 7z)
Add straight across:
2x - 6x = -4x
5y - 4y = y
-z + 7z = 7z - z = 6z
-4x + y + 6z is your answer.
