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.

[[4, 31, -29], [-5, 40, -8, -9], [-40, 16], [-32, 1, 10], [-1, 23, -43], [-12, 48], [-7, -1, -19]]
[-3596, -14400, -640, -320, 989, -576, -133]

[[-20, 50, -49, -10], [3, 1, 48], [-9, -31, -28, 1], [-39, -32]]
[-490000, 144, -7812, 1248]

[[16, -38, 40, -32], [-15, -44, 39, -1]]

[778240, -25740]
