Simplify (-4r⁵)(2r⁸)

• -8r¹³
• -2r¹³
• -8r⁴⁰
• -2y⁴⁰

 $\sqrt{x^5}$  

Write in exponential form:

•  $x^{\frac{1}{5}}$  
  

•  $x^{\frac{2}{5}}$  

•  $x^{\frac{5}{2}}$  
  

•  $x^5$

According to exponent rules, when we raise the coefficients to a power we _______ the exponents.

• add
• subtract
• multiply
• divide

Simplify:  $\frac{x^2y^5}{x^9y^5}$  

•  $x^2$  

•  $\frac{1}{x^2}$  

•  $\frac{1}{x^7}$  

•  $x^7$  

3⁴ is bigger than 4³.
