  1. 11.2A Simplify and Multiply Square Roots

  2. Squaring a Number When a number is squared, it is multiplied to itself: 1 5 5 25 -3 -3 9 Notice squaring any number always results in a ___________________ number. positive

  3. Taking the Square Root of a Number Just as subtracting is the opposite of adding and dividing is the opposite of multiplying, the opposite of squaring is ____________ ______________. square rooting

  4. Ex 1: Find the square roots of the following numbers: 1 3 m 23 Not possible!

  5. Ex 2: Find the following: (Think of the negative sign in front as just being negative one multiplied to the positive root.) –5 –23
