hi acid,

Lets take an example,
say 2^3^2 = ?.Well the correct answer is 2^9.I hope the solution is clear to you now.
Anyways,the answer I figured out is 2^8.

The brackets seem to create a little bit of confusion.
I also arrived at a different answer after considering ((4-1)^2/2^3-2) as power of 2.
Plz Help.
