3. index Radicand Radical

4.  Index: the index is the part of the equation that tells yow how many kind you are looking for Example:  Since there are two 3s the 3s can come out of the radicand but you only write it once. 33 3x3=9 33 3 = 3

7. Answer worked out and explained on next slide

9.  When multiplying radicals you have to check if the indeces and radicands of both radicals match.  Use the product rule. Ex. Different indeces

10. Answer worked out and explained on next slide

12.  When dividing radicals you have to check if the indeces of both radicals match.  Then, use the quotient rule: Ex.

13.  NOTE:  Multiply the numerator and denominator by the denominator. This causes the radicals on the bottom to cancel out to just a WHOLE number. Only do this if necessary. If there isn’t a radical in the denominator, disregard this.

16.  Steps: 1. Simplify ALL radicals 2. Combine "like terms“. Like terms = same index and same radicand. **If you don't have like terms, just leave it alone! No one wants to be forced together!**

24. STEPS: 1. Isolate the radical 2. Raise everything on both sides of the equal sign to the power of the index(see page 3 if you already forget what this is) 3. Solve for x  Ex.

25. 1. Raise everything on both sides of the equal sign to the power of the index(see page 3 if you already forget what this is) 2. Solve for x  Does this look familiar? It’s just like solving equations with radicals on one side except you don’t need to isolate the variable. Ex.
