Question 8125: An answer in my Algebra book contains the following exponential notation:
(-1/2)^9. This is shown as equaling (-1/2^9). I am familiar with exponential notation that has integers with fractional exponents but I do not know how this negative fraction with the interger exponent outisde of the parenthesis becomes minus 1/2 with the 9 now the exponent over the 2 in the denominator within the parenthesis. So, how does (-1/2)^9 become (-1/2^9)?
