Proof of limits with fraction

  1. Oct 20, 2009 #1
    prove that limit of --- (x[tex]^{n}[/tex]-a[tex]^{n}[/tex])
    ---------- ---------------- (x-a)
    when " x " tends to " a "

    equals to ---- n.a[tex]^{n-1}[/tex] ----- ****where " n " is a fraction..

    we have been given this and i've got no idea on how to prove it although i can do sums with this equation when " n " is a fraction

    PS this is my first post and i have no experience in witing equations in posts ..sorry if i've done any mistakes.
