$Simplify\ \left(3x^4\right)\left(2x^3\right).\ \ \$ 

 *Reminder:There are no exponents outside the parentheses. 

 $\frac{x^8}{x^4}$  Simplify

Simplify $\left(5y^2\right)\left(-7xy^3\right)$  

 $\frac{12x^4}{3x}$  

 $\frac{20x^3}{4x^3}$  

Anything to the power of zero is equal to...

Example:   $x^0\ \ \ \ or\ \ \ \ 4^0$  

Simplify   $\frac{27x^3y^6}{9xy^2}$  

Simplify   $\left(x^2y^3\right)^4$  
*Reminder: there are exponents inside AND outside the parentheses. You are raising a power to another power. 

Simplify $4x^2\left(-2x^3y^5\right)$  

Simplify $\frac{4^7}{4^5}$  

Simplify   $\frac{-30a^7b^3}{-5a^2b^2}$
