8. BASE Exponents tell how many times a number, called a BASE, is used as a factor. 7² = 7 x 7 In 6 x 6, 6 is used as a factor twice. When you compute 6 x 66²SQUARE of 6. 6 x 6 or 6², you are finding the SQUARE of 6. 6 6

9. 36, 49, and 625 are called PERFECT SQUARES, because they are the squares of whole numbers. Numbers like 36, 49, and 625 are called PERFECT SQUARES, because they are the squares of whole numbers. 6 6 PerfectSquare 6 is the number you would square to If 6 is the number you would square to find 36, then 6 is the square root of 36. 6² = 36 √36 = 6

10. What number would you square or is the square root of 9? 9 3 3 A radical sign ( √ ) is placed over a number when the square root is requested.

11. Construct a Square Root Chart with your partner showing the numbers that 1-20 are the square roots of! Example Square Root √ 1 1 √ 4 2 √ 9 3 √ 16 4 √ 25 5

12. What number would you square or is the square root of the following numbers: 1) √ 81 = 2) √ 121 = 3) √ 49 = 4) √ 196 = 9 11 7 14 ( 9 x 9 ) ( 11 x 11 ) ( 7 x 7 ) ( 14 x 14 )

13. If a number is not a perfect square, its square root can be estimated by finding two numbers on either side of that number. The estimated square root would be a number between the two numbers. Square Root √ 1 1 √ 4 2 √ 9 3 √ 16 4 √ 25 5 √ 20 4.5 about 4.5
