Under the Constitution, what is one power that belongs to the federal government?

The power to print money belongs exclusively to the federal government as stipulated in the Constitution. This authority is granted to provide a uniform currency across the entire nation, which is essential for maintaining a stable economy and facilitating interstate commerce. The federal government, specifically through the Department of the Treasury and the Federal Reserve System, controls the issuance of currency and manages the money supply.

Conducting elections, setting marriage laws, and establishing schools are responsibilities typically managed at the state or local level, reflecting the federal structure of government where certain powers are decentralized to allow for varied local governance suited to regional needs.
