To solve this expression, we need to follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

Let's break down the expression step by step:

First, we simplify the expression inside the parentheses:
(2 mu 16 + 2 mu 17) = 32 + 34 = 66

Now, we can rewrite the expression as:
(17 . 2 mu 0 .4 mu 5 - 2 mu 22) : 66

Next, we perform the multiplications and divisions from left to right:
17 . 2 = 34
0 . 4 = 0
34 mu 5 = 170
2 mu 22 = 44

Now, we substitute these values back into the expression:
(170 - 44) : 66

Next, we perform the subtraction:
170 - 44 = 126

Finally, we perform the division:
126 : 66 = 2

Therefore, the final answer is 2.
