Answer: 
Explanation:
The simplification of that expression is done in this way:
1) The negative sign is placed in front of the whole fraction
2) 27 is divided by 3 resulting in 9: 27 / 3 = 9
3) x^2 on the numerator cancels out with x^2 of the denominator
4) z on the numerator is cancelled out with 1 z of the denominator and the result is z^5 in the denominatoir.
All that yields to :
9
- --------
z^5
Using the math editor it is:
