If Z=1/2 what is the greatest value of the expression -(z^2z^-4)^-3?
------------------------
-(z^2z^-4)^-3
Simplify:
= -(z^-2)^-3
------------------
= -(z^6)
---
Let z = 1/2
---
You get: -(1/2)^6 = -1/64

If z = 1/2, it's = -1/64
----------
What does "greatest value" mean? It's -1/64, the only value when z = 1/2.
