Binomial theorum, when k is a multiple of x

  1. Sep 10, 2008 #1
    kx = x !/r! (x – r)! kx− r

    is that right?

    The right side of your equation is confusing. Put in some parentheses.

    The thunbnail is hard to read. In the second equation there are terms with k to some exponent. It is hard to read these exponents. Also, what is the question - prove the second equation holds?
