    EDIT:
    What happened? Your previous post dissapeared (also the title)?

    What do you have to do now?

    Laws of exponents say that [(x+1)^2]^3 = (x+1)^6]. If you want to expand it use the binomial theorem

    \sum_{k=0}^n (1+x)^n = \binom{n}{k}x^k

    Re: [(x+1)^2]^3

    This whole thread is causing confusion due to OP edits, lack of a problem statement etc. People are wasting their time as a result. Thread cloed.

    @OP: Post your question properly. Include all of the question, including the problem statement.
