I really enjoyed learning rational exponents because they seemed very difficult though in reality they are very simple to understand. For this question I took the 3 (denominator) and made that into a cubed root (using flower power). I then put the 125 as the radicand and the 1 (numerator) as an exponent for 125. The next step I did was that I found the cubed root of 125, which is 5 (because 5•5•5=125). Then finally I had 5 to the power of 1 that was left, which is 5. So 125  to the power of 1/3 is 5!
