Parentheses matter in exponents. Consider ((-5)^{3})^{4} our example and (-5)^(3^{4}). The first is (-5)^{12}, the second (-5)^{81} Nov 19 | Michael F. Comment
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}. Nov 18 | John M. Comment Comments -5^{12 }≠ (-5)^{12} You evaluate the exponent first in -5^{12} and get a negative number, since it's (-1)(5^{12}) I'm sure it was just a typo. Nov 19 | Jason S. Comment
