Simplify the following, 125^-2/3

1. The minus sign indicates that the answer is a reciprocal meaning basically 1 over.2. Next, on inspection of the fraction, the 2 on top means that you square the number, times it by itself. 3. The 3 on the bottom of the fraction means that the number is then cube rooted, finding the number that timed by itself 3 times makes the original number. 4. If done correctly you should arrive at the answer of 1/25.
