Well, that was the

**application**of the Ratio Test.

You did not make any**conclusion**.

Why do you require simplification? Let's draw some conclusions without it. It looks to me like just about every piece is approaching unity. Where does that leave us?

Note: Nice screen name. I wish more folks felt that way about mathematics! (Clapping) Why do you hoist a China flag and speak from Viet Nam?

Other Note: From your experience, does whatever culture you know tell women and girls that they can't do math? Obviously, that would be a silly thing to tell**you**, but it may remain a common cultural message.
