1. Vocabulary Square Root: If A = s 2, then s is a ____________________ of A. example: 25 = 5 2, 5 is a square root of 25 Cube Root: If V = s 3, then s is a __________________ of V. example: 27 = 3 3, 3 is a cube root of 27 square root cube root

2. You need to remember: Perfect Squares 1 = 1 x 1 = 1 2 4 = 2 x 2 = 2 2 9 = 3 x 3 = 3 2 16 = 4 x 4 = 4 2 25 = 5 x 5 = 5 2 36= 6 x 6 = 6 2 49= 7 x 7 = 7 2 64= 8 x 8 = 8 2 81= 9 x 9 = 9 2 100= 10 x 10 = 10 2 Radicals (square roots) √1 = 1 √4 = 2 √9 = 3 √16 = 4 √25 = 5 √36 = 6 √49 = 7 √64 = 8 √81 = 9 √100 = 10

3. We discussed earlier that the inverse of an operation would “undo” that operation. The inverse operation of squaring a number is the square root ( √) of that number.

4. 25 64 9 9 5 125 4 16 81 729 3 27

5. 525 You probably chose 5 because 5●5=25 You could also say that the square root of 25 equals 5

6. 464 You probably chose 4 because 4●4●4=64 You could also say that the cube root of 64 equals 4

7. Because 14●14=196 Because 6●6●6=216

8. Find the missing value: This is also the same as solving the equation:

9. Are there any other values for x that would also be a solution to this equation? x could also equal -10 because -10●-10 = 100? This symbol means positive or negative

10. Find the missing value: This is also the same as solving the equation:

11. Are there any other values for x that would also be a solution to this equation? Could x also equal -2 ? No, because -2●-2●-2=-8

12. 12

13. Simplify: 25+15 40

14. Simplify: 196 + 5 201

15. Simplify: -4 + 9 5
