Answer 2

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

|-3,1| represents the absolute value of -3 + 1, which is |-2|, and since the absolute value of any negative number is its positive counterpart, |-2| equals 2.

|-1 9/31| is a mixed number. To convert it to an improper fraction, we multiply the whole number (-1) by the denominator (31) and add the numerator (9). The result is -40/31.

|-1 1/3| is also a mixed number. Converting it to an improper fraction, we multiply the whole number (-1) by the denominator (3) and add the numerator (1). The result is -4/3.

|-3/4| is already in fraction form.

Now, let's substitute the values into the expression:

2 * (-40/31) * (-4/3) * (-3/4)

To simplify the multiplication, we can cancel out common factors:

2 * (-1) * (-1) * (-1) * (-1) * (-1) * (-1) = 2

Therefore, the result of the given expression is 2.
