Exponent Basics

Exponent Basics

By the end of the lesson, ​you will be able to apply the algorithm for adding & subtracting decimals using mathematical reasoning and problem solving.

Exponent Rules

• ​​Watch the video

• ​Record the examples on your guided notes page as you watch

• ​Ask questions if you don't understand!!

​Perfect Squares & Cubes

​Please record (write) the perfect squares and perfect cubes, 1-20 on the back of your notes paper. 1-13 is provided on the right, but you will need to continue with 14-20 as well.

​

Feel free to ask questions if you don't understand how to find the values.

Multiple Choice

$$10^3=$$  

• $$10\times10\times10$$  

• $$10\times3$$

Multiple Choice

If a number or variable does not have an exponent, we can assume the exponent is:

• 0

• 1

Multiple Choice

$$y^0=$$  

• y
