    Expansion of Binomials???

    Okay im taking a data management course and im having trouble with...

    1) For the expansion of (x + y)17

    A. How many terms are there?

    B. In the term containing y3, what is the coefficient?

    C. What is the value of k in the term XkY8

    D. What is the 13th Term?

    E. What is the sum of the exponents on the x and on the y in any term?

    2) Expand the following binomial using the binomial theorem
    A. (X + (2/x)^4

    i have the answers but im stumped on the solutions since im having difficulty solving it..

    These are pretty basic questions about the Binomial Theorem. You could try looking here: The Binomial Theorem and see if it helps.

    A) There would be 18 terms.

    For the rest I would suggest you use the Binomial Theorem to answer the questions
