Which expression is equivalent to ^3 square root 10x^5/54x^8 ?
2 answers:
The first step for solving this expression is to reduce the fraction with 
.
![\sqrt[3]{ \frac{10}{54 x^{3} } }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B10%7D%7B54%20x%5E%7B3%7D%20%7D%20%7D%20)
Reduce the fraction with 2.
![\sqrt[3]{ \frac{5}{27 x^{3} } }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B5%7D%7B27%20x%5E%7B3%7D%20%7D%20%7D%20)
To take a root of a fraction,, you must take the root of the numerator and the denominator separately. This changes the expression to the following:
![\frac{ \sqrt[3]{5} }{3x}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%5Csqrt%5B3%5D%7B5%7D%20%7D%7B3x%7D%20)
Since we cannot simplify this fraction down any further,, the correct answer to your question is going to be option D,,.
Let me know if you have any further questions.

Answer:
f^(-1)(x) = \frac{-1}{5} (x+4)
Step-by-step explanation:
Given is a function
To find its inverse.
We must check whether f is one to one or onto first
If -5x1-4 = -5x2-4 we get x1=x2
Hence f is one to one
Also for every f(x) we can find a x so f is onto.
So inverse exists
Let
Replace x by f inverse and y by x
