TRY IT:

Rewrite this and explain why this rule works.

( w / z )^3


Here's a messier one...

We're going to need our old rules too!

Let's rewrite this guy:

( ( x w^3 ) / ( -5 z^4 ) )^2

We just hammer away at the rules a little at a time...

( ( x w^3 ) / ( -5 z^4 ) )^2 = ( x^2 w^6 ) / ( 25 z^8 )
