whenever there is a negative exponent you can change it to positivr exponent by putting it as One devided by if
in your example = 1/(3/2)^3
= 1/ (27/8) = 8/27

What you do is this:
3/2 raised to negative 3rd power.
When something is raised to NEGATIVE power, it is receprical. That means 2^-3 is 1/(2^3).
Using this example, you can tell (3/2)^-3 is 1/((3/2)^3), which is 1/(3^3/2^3) = 1/(27/8) = 8/27.
Your answer is 8/27
