Question

Use the ratio test to determine convergence or divergence. Sigma n!/n^n; n = 1; to infinity.

Answer 1

(xz-zy)^3

evaluate the expression for: x=3,y=2,z=5

(15-10)^3 = 5^3 = 125

Answer 2

seems to converge

Answer 3

Yes, it converges, but I have to just show work. Don't know how to start.
