When you raise a monomial to a power, distribute the power and _______________________ the exponents.

• add

• subtract

• multiply

Simplify:

 $\left(xy^3\right)^2\left(x^2y\right)^3$  

(Hint: Make sure all variables have an exponent. Distribute the exponents and multiply the powers. Don't forget to add exponents of like variables as your last step.)

•  $x^8y^9$  

•  $x^7y^8$  

•  $\left(x^2y^6\right)\left(x^6y^3\right)$

Simplify:


 $\frac{1}{2}\left(4ab^2\right)^2\left(a^4b^5\right)^3$  


(Hint: Make sure all variables and coefficients have an exponent. Distribute the exponents and multiply the powers. Then add exponents of like variables.)

•  $4a^{10}b^{11}$  

•  $8a^{14}b^{19}$  

•  $8a^{24}b^{60}$
