[Solved] Overbrace on Powers

Leandro Abib Asks: Overbrace on Powers
How can I make an overbrace on powers without it being buggy. Example:

Code:
$$
begin{array}{ccc}
    (x^{m+1})^n &=& underbrace{x^{m+1} cdots x^{m+1}}_{n} \[.8cm]
    &=& x^{overbrace{(m+1)+cdots+(m+1)}^{n}} \[.8cm]
    &=& x^{overbrace{(m+cdots+m)}^{n}+overbrace{(1+cdots+1)}^{n}}
end{array}
$$

The image below ilustrate the code above.


Output for the code above

Anyone knows how to solve this issue?

Thanks in advance.
