please explain how to do with each part.

Find the Taylor series for x) = V} centered at a = 4. Find the interval of convergence of your series. Find the Taylor polynomial of degree three and the remainder associated with this approximation, for x E [3, 5]. Use the Taylor polynomial of degree three to approximate V3. Give an exact answer. (You can use a calculator once you have an exact answer, if you are curious about the number as a decimal, but that isn't worth any credit.) Give a justication for each step of your work
