What are enumerated concurrent and reserved powers?

Enumerated powers are those explicitly granted to the federal government by the U.S. Constitution, such as the power to tax, regulate commerce, and declare war. Concurrent powers are shared by both federal and state governments, including the ability to levy taxes and enforce laws. Reserved powers, on the other hand, are those not delegated to the federal government nor prohibited to the states, allowing states to exercise authority over matters like education and local law enforcement. These concepts help define the distribution of power within the U.S. federal system.
