1) -2b × (-3) × 125 / 5 × (-75b)

First, simplify the multiplication:

-2b × (-3) = 6b
125 / 5 = 25

Therefore, the expression becomes:

6b × 25 × (-75b)

Now, multiply the remaining terms:

6b × 25 × (-75b) = -11250b^2

Final answer: -11250b^2

2) -33a × 6.5b / 0.5b × 1.3 × (-11a)

First, simplify the division:

6.5b / 0.5b = 13

Therefore, the expression becomes:

-33a × 13 × 1.3 × (-11a)

Now, multiply the remaining terms:

-33a × 13 × 1.3 × (-11a) = 4782.3a^2

Final answer: 4782.3a^2

3) -88ab × 9.3 / 3.1 × (-6.6) × (-4ab)

First, simplify the division:

9.3 / 3.1 = 3

Therefore, the expression becomes:

-88ab × 3 × (-6.6) × (-4ab)

Now, multiply the remaining terms:

-88ab × 3 × (-6.6) × (-4ab) = 862.08a^2b^2

Final answer: 862.08a^2b^2
