To simplify the expression, let's break it down step by step:

First, let's simplify the exponents:
(-1/2)^3 = -1/8
(3/4)^3 = 27/64
(-2)^2 = 4
(-1)^5 = -1
(3/4)^2 = 9/16

Now, let's substitute these values back into the expression:
Q = (-1/8) - (27/64) * 4/2 * (-1) + 9/16 - #/8

Next, let's simplify the multiplication and division:
Q = (-1/8) - (27/64) * 2 * (-1) + 9/16 - #/8
Q = (-1/8) - (27/32) * (-1) + 9/16 - #/8
Q = (-1/8) + 27/32 + 9/16 - #/8

Now, let's find a common denominator for the fractions:
Q = (-2/16) + 27/32 + 18/32 - #/8
Q = (-2/16) + (27 + 18)/32 - #/8
Q = (-2/16) + 45/32 - #/8

Finally, let's simplify the fractions and combine like terms:
Q = (-1/8) + (45/32) - #/8
Q = (-1/8) + (45/32) - #/8
Q = (-1 + 45 - #)/8

Therefore, the simplified expression is Q = (44 - #)/8.
