Parentheses matter in exponents. Consider ((-5)3)4 our example and (-5)^(34).  The first is (-5)12, the second (-5)81

yes, karen, they matter.  the order of operations is defined by the parentheses.  In this case:
you would cube -5 and then raise that value to the 4th power.  
To me, this is an acceptable answer.  However, your teacher might want you to simplify this to -512


-512 ≠  (-5)12
You evaluate the exponent first in -512 and get a negative number, since it's (-1)(512)
I'm sure it was just a typo.
