A nice auxiliary would help:
showEqn :: Int -> [Double] -> String
showEqn i vs = ...
(add,ans) = (init vs, last vs)
Then you can half the complexity. There are probably a few useful
functions that aren't in the standard libraries (consperse, joinWith
etc) that you could make use of.
You seem to be doing take 8 on the double - what if the double prints
out more information than this as the result of show?
1000000000000000000 could end up a bit smaller.
