Hey, when you take the exponents, start from the top and make your way down or just write it using lots of parenthesis and solve inside each parenthesis and make your way out.

(2 ^ ( (4-1)^2))) / (2^(3-2))

First, get rid of simple operations that are in the parenthesis :

(2 ^ (3^2)) /( 2 (1))

Now, again :

(2^9) / 2

Then :

2^8
