4.8 Whole # Simplify

 $3^2\cdot3^3$  

• Can we simplify each term first?

•  $3^2\rightarrow9$  

•  $3^3\rightarrow27$  

•  $9\cdot27\ =\ ?$  

 $10^3-5^3$  

• Simplify each of them separately

•  $10^3\rightarrow1000$  

•  $5^3\rightarrow125$  

•  $1000-125\ =\ ?$  

 $24-\left(8-4\right)^2\cdot3$  

• PEMDAS - write on your whiteboard what each letter stands for

• P - Do we see something inside parentheses?

•  $24-\left(4\right)^2\cdot3$  What letter comes next?

• E - any exponents?

•  $24-16\cdot3$  

• What is our next step?

•  $24-48$
