Question 307135: Good morning!
An interesting radical conundrum for me:
SIMPLIFY: fourth root of (9 / z^5) or (9 / z^5)^(1/4)

I broke it down: (9)^(1/4) / (z^5)^(1/4)
Then I multiplied top and bottom by (z^5)^(1/4)
Result: (9z^5)^(1/4) / z^5
Simplify: z(9z)^(1/4) / z^5
Again: (9z)^(1/4) / z^4

I believe I worked this correctly, but I have doubts when I read the answer sheet in the book with the solution: (9z^3)^(1/4) / z^2
Did I miss a step?
Thanks in advance... George
