Parentheses matter in exponents. Consider ((-5)^{3})^{4} our example and (-5)^(3^{4}). 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 -5^{12}.

^{12 }≠ (-5)^{12}^{12}and get a negative number, since it's (-1)(5^{12})
