From an advanced calculus book

a) If q(n) = byn* + Bk-1n*-1+...+ b1n+ bo is a polynomial in the variable
ne N with be # 0, show that there exists N EN such that n > N implies
q(n) # 0.
b) Show that
aknk + ak-1nk-1+...+ a1n + ao
lim
n-00 bknk + bk-1nk-1+
+ bịn + bo
bk
provided that b +0 and k is a positive integer.
