Factor and Simplify Algebraic Expression

I am doing some review questions for University and don't recall how to answer a question like this (my answer should only have positive exponents) .... Thanks!
$ (x+3)^\frac{-1}{3} $ $ -(x+3)^\frac{-4}{3} $

$ (x+3)^\frac{-1}{3} $ $ -(x+3)^\frac{-4}{3} $

$(x+3)^{-\frac{1}{3}} - (x+3)^{-\frac{4}{3}}$

common factor for both terms is $(x+3)^{-\frac{4}{3}}$ ...

$(x+3)^{-\frac{4}{3}}[(x+3) - 1]$

$(x+3)^{-\frac{4}{3}}(x+2)$

$\frac{x+2}{(x+3)^{\frac{4}{3}}} $

$ (x+3)^\frac{-1}{3} $ $ -(x+3)^\frac{-4}{3} $ = $\frac{1}{(x+3)^\frac{1}{3}}-\frac{1}{(x+3)^\frac{4}{3}}= \frac{(x+3)-1}{(x+3)^\frac{4}{3}}=\frac{x+2}{(x+3)^\frac{4}{3} }$
