In this task, you are given a list. This list contains many lists of integers. The list is several items written within a []. Your task is to find the maximum number among the members of each inner list. The output should be a list comprised of the maximums with the same order as the internal lists.

[[-117, -110, 36, 18], [-15, 40, -140], [-33, 79, 8, 42, -4, 84]]
[36, 40, 84]

[[83, -95, 37, -7], [33, -23, -133, -134, 77], [52, -161, 1, 34, -123, -29], [-130, 51, 97, -29], [-14, 36, -88, 49, -199]]
[83, 77, 52, 97, 49]

[[75, -57], [-98, -47, -64, -129]]

[75, -47]
