Not sure how to begin actually...

I've tried taking logs of both sides and using sterling's approximation but it came to nothing... :(

They are using things like (N/2+m)!/(N/2)!=(N/2+m)*(N/2+(m-1))*...*(N/2+1). Expand the right side keeping only the two highest powers of N/2. You get (N/2)^m+(m+(m-1)+...+2+1)*(N/2)^(m-1).
