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.

[[11, -21, 50, -45, 41], [42, 10, 15, 38]]
[21309750, 239400]

[[-16, -46], [-35, 0, -29, 13], [-26, 1, -16], [18, -37, 13], [-7, 49]]
[736, 0, 416, -8658, -343]

[[-10, 41, -18, 17, 22], [38, -22, -25, 47], [30, 40, -7]]
