What's our "shortcut" for thinking of this property?
 $\left(a^mb^n\right)^p\ =\ a^{mp}\ b^{np}$  

• It's like "distributing" the power

• We add the powers together

• We divide the powers

What's our "shortcut" for thinking of this property?
 $\left(\frac{a^m}{b^n}\right)^{p\ }=\ \frac{a^{mp}}{b^{np}}$  

• It's like "distributing" the power to each part of the top and bottom

• We subtract m and n, then multiply by p

• We exponent-ize everything
