Final answer:
Unable to provide the inverse Laplace transforms due to typographical errors in the expressions provided by the student. Accurate expressions are necessary to match them with known forms and apply standard methods for inversion.
Step-by-step explanation:
The student has asked for help in finding the inverse Laplace transform of certain expressions. As the expressions provided do not fit standard forms, and there seems to be a misunderstanding or typographical error, it's unclear what the correct expressions are. Consequently, without the correct format of the Laplace transforms provided, it is not possible to give a direct answer regarding their inverse Laplace transforms.
It is crucial to ensure that the Laplace transforms are given accurately to find their inverses. Inverse Laplace transforms are usually found using standard tables or applying complex variable techniques, and specific forms are essential to match the transformed functions with their corresponding originals in the time domain.
If the student can provide corrected expressions, we could proceed with assisting in finding the inverses using standard methods and known properties of the Laplace transforms.
