Calculating Height of a Twice-Daily Orbit Above Earth's Surface

Apart from the fact that you again have way too many significant digits. You really do not have more than two at best. I suggest writing the answer in units of Mm (megameter) or, even in units of the Earth's radius. Giving nine significant digits you are essentially saying you know all the input variables to a precision that would be the same as knowing your height with a precision of the size of an atom. This is completely unreasonable.
I used meters to try to keep the units the same.
So if my smallest significant figures is 9.8, with 2 significant digits, then the final answer would be 2.6E7 m?

I suggest you get comfortablr with prefixes. That is what they are for.

You also forgot to remove the Earth radius now.

I have subtracted the radius with Earth's radius in the previous post.

Isn't mega meter the same thing as kilometer? I don't understand the difference? So your'e putting it in kilometers but you write it as mega meters?

No, mega and kilo are different prefixes. Why would they be the same? While kilo denotes ##10^3##, mega denotes ##10^6##.
