1. 7.4 Dividing Radical Expressions  Quotient Rules for Radicals  Simplifying Radical Expressions  Rationalizing Denominators, Part 1 7.41

2. The Quotient Rule for Radicals 7.42

3. Simplify  By taking roots of numerators & denominators 7.43

4. Simplify  By combining and simplifying under the radical 7.44

5. A Radical Expression is Simplified When: 1.Each factor in the radicand is to a power less than the index of the radical 2.The radicand contains no fractions or negative numbers 3.No radicals appear in the denominator of a fraction 7.45

6. Rationalize the Denominator  By simplifying inside the radical  Think about what is needed on the bottom! 7.46

7. Rationalize the Denominator  By simplifying outside the radical 7.47

8. Rationalize the Numerator ?  Required only for Calculus, but learn the way: 7.48
