I'm struggling with some exponents, anyone care to help?

-(-c^{4})^{-4}) = 1/c^{16 }however Maple 17 returns a different result -(-c^{4})^{-4}) = -1/c^{16 }

I have attached a PDF of a Maple page if anyone is interested to take a look and possibly point me in the right direction. Thanks in advance, I'm pretty sure I'm missing some concept regarding the negation and the parentheses, but not sure what it is.
