Lesson 40 Warm Up

The _______ is the number that tells how many times the base of a power is used as a factor.

• Base

• Power

• Exponent

• Raised to

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

•  $20x^8y^{12}$  

•  $9x^2y^3$  

•  $20x^6y^7$  

• None of the Above

Simplify:  $\frac{24x^3y^6}{36x^5y^3}$  

•  $\frac{2}{3}y^3x^2$  

•  $\frac{2y^3}{3x^2}$  

•  $\frac{2}{3}xy$  

•  $\frac{2}{3x^2y^3}$  

Simplify:  $\left(-3\right)^2-3^2$  

• 1

• 0

• 3

• -3

Compare:  $4^2+\ \sqrt{36}\ and\ -\left(-3\right)^2\ +\sqrt{25}$  

• <

• >

• =

• No Solution
