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.

[[2, 10, 18, 21, -17], [13, -10, 39, -37], [-27, 9], [9, -15, -29]]
[-128520, 187590, -243, 3915]

[[-3, -18, 24], [44, 26], [18, -21], [-41, -21, -47, 38], [-4, 9, -18, -50], [-10, 22, 26, -2, 23]]
[1296, 1144, -378, -1537746, -32400, 263120]

[[-18, -2, -20, -45, -40], [0, -33, 42, -18]]
