Final answer:
The Louisiana Purchase increased the power of the federal government by expanding its territory and strengthening its authority.
Step-by-step explanation:
The Louisiana Purchase did increase the power of the federal government.
With the purchase of the Louisiana Territory from France in 1803, the United States more than doubled in size. This acquisition gave the federal government control over a vast territory, which included important trade routes, natural resources, and valuable land for expansion. It also allowed the federal government to extend its jurisdiction over new territories and ultimately helped to solidify its authority over the nation as a whole.
Furthermore, the Louisiana Purchase demonstrated the federal government's ability to negotiate and conduct international diplomacy, further enhancing its power and influence on a global scale.
