which of these powers is considered an implied power? raising taxes regulating trade creating a national bank declaring war

The power considered an implied power among the options given is "creating a national bank." Raising taxes, regulating trade, and declaring war are examples of expressed powers explicitly granted to Congress by the Constitution. In contrast, the creation of a national bank is not mentioned explicitly in the Constitution but is considered an implied power derived from the expressed powers to tax and regulate commerce. This was famously upheld in the Supreme Court case McCulloch v. Maryland, where the Court recognized Congress's authority to establish a national bank as necessary and proper to carry out its constitutional powers.
