Answer:
1/27
Explanation:
Ok this looks like a huge number but if you break it into smaller numbers its easier to work with
3^5=243 so we can write...
(3^5)^-3/5
Rule of exponents state that you can multiply powers
5*3/5=15/5=-3
Because its negative we would make it over 1
1/3^3
And simplify...
1/3*3*3
1/27
