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.

[[-8, -19, 2], [16, -4, -28, 50], [40, 36, -48, 31, -36], [44, 41, -50, 47]]
[304, 89600, 77137920, -4239400]

[[41, -37, -30, -25], [22, 0], [-43, 23, -30]]
[-1137750, 0, 29670]

[[-24, 6, 44], [-3, 34], [28, 31, -48, -38, -32], [-32, -1, -16]]
