That's the only bracket the question shows. As I typed it.

2^(4-1)^2/2^3-2
simplify:-
2^3^2/2^1
2^9/2^1= 2^8

Got it. Thanks

I'm not sure this is right.

If the problem reads

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

then you'd have

2^(3)^2
-------
8 - 2

or

2^9
---
6

or

256/3.

If the problem reads

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

then you'd have 2^9 / 2^1, or 2^8.

But frankly I don't think it's either of these. As written, this question would be interpreted by most computers (such as Wolfram Alpha) as

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

or 2^6 - 2, or 62.

Seems unclear to me. I'd try to avoid questions that don't have proper exponent formatting, as they may not come from reliable sources.
