What is 5 raised to the 2.5 power?
Veronica.
not exactly. you could write it using radicals for the exact answer. that would be $\displaystyle 5^{2.5} = 5^{5/2} = \sqrt {5^5} = \sqrt {3125}$
otherwise, you could get a decimal approximation by hand. but that is way more work than this is worth, and i doubt your professor would want you to do that
