Hi,
find the specified terms in the expansion of the polinomial.
(x^2y^3 + 1/xy)^11  , {{{7th}}} term
  {{{11C6*(x^2y^3)^5(1/xy)^highlight(6) = 462x^4y^9}}}
2.(b^2 x + c^3 y^2)^19 , middle term.  
(20 terms, thus 2 middle terms, 10th and 11th terms)
 {{{19C9(b^2x)^10(c^3y^2)^highlight(9)}}}   and  {{{19C10(b^2x)^9(c^3y^2)^highlight(10)}}}
