    [tex] (a+b)^{2}=a^{2}+2ab+b^{2} [/tex] !!

    Now,are u interested in that

    [tex] \left[(a+b)^{2}\right]^{15}=(a+b)^{30} [/tex]

    ,or in that

    [tex] (a+b)^{15} [/tex]

    Do you know something about the Newton's binomial formula ...?

    You know of Newton's binomial formula.
    Your teacher is testing you whether you understand how to apply that formula or not.
