160:{17+[2³.5&(12+2⁸:2⁵)]}

First, let's break down the expression inside the brackets:

12 + 2⁸:2⁵ = 12 + (2⁸ ÷ 2⁵) = 12 + (256 ÷ 32) = 12 + 8 = 20

Now, let's calculate the expression inside the square brackets:

2³.5 & 20 = 8.5 & 20

To calculate the bitwise AND operation, we convert the numbers to binary:

8.5 = 1000.1
20 = 10100

Performing the bitwise AND operation:

1000.1
& 10100
---------
10000

The result is 10000, which is equal to 16 in decimal.

Now, let's calculate the expression outside the brackets:

17 + 16 = 33

Therefore, the final result is 33.
