In this task you will be given a list of lists, of numbers. For every inner list, you should multiply every number in that list and put the results in your answer. The output should be a list of numbers with the same length as the number of the lists in the input list.

Let me give you an example: [[5, 1, 2, 7], [0, 4, 6, 6], [7, 8, 10, 3, 1], [1, 4]]
The answer to this example can be: [70, 0, 1680, 4]
Here is why: The second list had zero so the second product is zero. Every product is calculated correctly: 5x1x2x7= 70, 7x8x10x3x1=1680, 1x4=4.

OK. solve this:
[[-11, -21], [-10, 38], [48, 5, -5, 2, -7], [38, 20], [-16, -26, -48, 7], [-30, 50, 30], [19, 16, -3, 41, 32], [-5, 2, 4, 9, 38], [6, -21, -28]]
Answer:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
