2 Definitions Square root: Perfect Square: Square of the Square Root Property: If A = s 2, then s is called a square root of A. Squares of whole numbers Examples: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169 For any nonnegative number n,

3 Examples It took 130 square yards of carpet to cover a square floor. Give the length of the room. Using the Radical symbol: Using a decimal approximation: 11.40 yards

4 Evaluate Estimate - give a rough estimate: -Use a calculator to get a good estimate: Between 2 and 3 2.236

5 Multiply without using a calculator A.) B.) C.) Solve x 2 = 52 Give the exact solutions: Give the solutions using a calculator: 11 20 * 11 = 220 7.21, -7.21
