Friday's Math Class

Hey Guys! Here are some things that we covered in class on Friday.

POD.

Promblem: Complete the table

x	4x	4 to the x power
1
2
3
4

Answer:

x	4x	4 to the x power
1	4	4
2	8	16
3	12	36
4	16	64

Use the table to guide your thinking when answering the following questions:
Why do we have exponents? How aer they useful? What general affects do exponents have?

Answer:

• simplify the promblem "Shorten the promblem"

• used for volume and area

• general effects:

• make numbers grow rapidly. Thats why we use them

• also an efficient way to communicate

Something to note: Dustin Short- he can tutor you Friday after school for those who need it in this class, it costs $10.00

1. ac to the 3rd power = 37
