Square Numbers

This is a review of what is a square number.  When you take a number like 2 and multiply it by itself, the answer is a square number.  That means that 4 is a square number.

If you have the number 20, it is NOT a square number.  Why?  It's because there is no number multiplied by itself to equal 20.

Examples: 

4 is a square number, because 2 x 2 = 4.

6 is NOT a square number, because there is no number multiplied by itself to equal 6.

8 is NOT a square number, because there is no number multiplied by itself to equal 8.

9 is a square number, because 3 x 3 = 9.

Question:
