Homework Statement
(9^(3/x))^4
(without calculator)
Homework Equations
a^n/m = m'root'a^n
The Attempt at a Solution
adding the powers: 3/x*4/1 = 12/x
9^12/x
x'root'9^12 = ?
----------------------
Ok, it's supposed to be 27, but how can you know something that are being rooted from x?
The calculator says it's 2.655 when I use the x'root'9^12 (It's incorrect and I'm not allowed to do that)
How does it get that from x? And what is the correct way to find it?
