    Term independent of x in binomial expansion, (but k is non-integer in expansion?)

    Hi I need help with a question as I am getting k as a non-integer when doing the binomial expansion.

    Question: Find the term independent of x in the expansion of:


    My attempt:




    Therefore term independent of x when

    but at this point k = 28/3 and I am not sure how to move forward.

    How do I solve this question?

    Thanks, so I guess to answer the question you would say the term independent of x is 0?
