What are the reserved powers as outlined in the tenth amendment

The reserved powers, as outlined in the Tenth Amendment, are all the powers that belong to the states because the Constitution does not delegate it to the government and does not prohibit them to the states. This statute was created to address states' fears that they could lose their powers to the government and to define those powers held by the state and those held by the government.

I believe the answer to that question are powers that are not delegated to the federal enlivenment and therefore granted to the states, as long as they are not prohibited by the constitution. Hope that answers your question
