I'm consistently getting confused on how to rearrange equations. For example, the following from an exercise that I'm attempting:

$\displaystyle x^\frac{1}{3} (10x^{2} - x^{-2}) $

simplifies to...

$\displaystyle 10x^\frac{7}{3} - x ^{-\frac{5}{3}} $

Would appreciate a step by step on this one please and if anyone can point me towards a general tutorial on this type of thing, I's be most grateful.
