8^1/3 means 3¬(cube root) 8
a^m/n means (¬(n root) a)^m
32^3/5 means (5¬(5 root) 32)^3
In Simpler Terms

a^1/3 means the cube root of a
and any number on top of the indices is the number the square root of the number is to the power of.
a^-1/2 means 1/a^1/2
or in other words 1 over the square root of a.
