Perfect Squares and Their Roots
Square Numbers?!?
How could a number also be a square? If you can arrange that number of items into a perfect square. Take the number 9 for example. You can take nine items and arrange them in a three by three square, so nine is a square number.
STEP 1: WATCH THE VIRTUAL CLASS VIDEO AND TAKE NOTES
Make sure to note the following:
The perfect squares from 0 to 100. It is not necessary that you memorize this list, but it is helpful for the non-calculator section.
The inverse, or opposite, of the second power.
