  3. Simplify = 2 = 4 = 5 This is a piece of cake! = 10 = 12

  4. Perfect Square Factor * Other Factor Simplify = = = = LEAVE IN RADICAL FORM = = = = = =

  5. Perfect Square Factor * Other Factor Simplify = = = = LEAVE IN RADICAL FORM = = = = = =

  6. Warm up • Simplify: • 1. • 2. • 3.

  7. Multiplying & Dividing Radicals Objective: To simplifying products and quotients of radicals.

  8. Multiplying Radicals * To multiply radicals: multiply the coefficients and then multiply the radicands and then simplify the remaining radicals.

  9. Multiply and then simplify

  10. Dividing Radicals To divide radicals: divide the coefficients, divide the radicands if possible, and rationalize the denominator so that no radical remains in the denominator

  11. This cannot be divided which leaves the radical in the denominator. We do not leave radicals in the denominator. So we need to rationalize by multiplying the fraction by something so we can eliminate the radical in the denominator. 42 cannot be simplified, so we are finished.

  12. This can be divided which leaves the radical in the denominator. We do not leave radicals in the denominator. So we need to rationalize by multiplying the fraction by something so we can eliminate the radical in the denominator.

  13. This cannot be divided which leaves the radical in the denominator. We do not leave radicals in the denominator. So we need to rationalize by multiplying the fraction by something so we can eliminate the radical in the denominator. Reduce the fraction.

  14. Simplify = X = Y3 = P2X3Y = 2X2Y = 5C4D10

  15. Simplify = = = =

  16. = = = =

  17. Warm up • Simplify • 1. • 2. • 3.

  18. Adding & Subtracting Radicals Objective: To simplify sums & differences of radicals.

  19. Combining Radicals + To combine radicals: combine the coefficients of like radicals
