First, let's simplify the expression inside the square brackets:
8 * 5 - 43 + 6 = 40 - 43 + 6 = 3 - 37 = -34
Next, let's simplify the expression inside the curly brackets:
27 / 9 * (-34) = 3 * (-34) = -102
Finally, let's simplify the entire expression:
(16 * 4) / 8 * (-102) = 64 / 8 * (-102) = 8 * (-102) = -816
So, the value of the expression (16 * 4) / 8[{27/9(8*5-43+6)}3] is -816.
