Well after isomorphism helped get me sorted out the other day I thought I had these Binomials licked BUT!!!!
When I tried this one I couldn't seem to get the right answer
Find the term x^44 in the following
(x^2 - 1/sq root x)^27
So thought I was doing well getting
this as the general term
(27 over r) ( x^2n-2r ) . (-x^-1/2r)
and the solving for r ie 5/2r = 27 but then of course r works out really ugly.
If someone prepared to have a go at helping I would be grateful
