| Slide 1 : Combining Radical Terms |
| What is a radical term? : It is a term which contains a radical. What is a radical term? |
| But what is a radical? : But what is a radical? A radical is another name for a square root. |
| Slide 4 : Okay—so a radical term . . . . . . is an term that contains a radical, or square root. Look! There goes one now! |
| Slide 5 : Consider these two expressions: |
| Slide 6 : What makes them different? What do they have in common? |
| Slide 7 : You may have noticed that the two expressions are really the same, if . . . |
| Slide 8 : If what? Under what condition would the two expressions be identical? |
| Slide 9 : The two expressions are identical when |
| Slide 10 : That means since you already know how to simplify the first expression . . . |
| Slide 11 : . . . then you also know how to simplify the radical expression . |
| Slide 12 : The rules that apply to combining like terms |
| Slide 13 : also apply to combining radical terms. |
| Slide 14 : also apply to combining radical terms. |
| Slide 15 : You can only combine radical terms when the radicands are identical. When what are identical? What is a radicand? |
| Slide 16 : The radicand is the number underneath the square root sign. |
| Slide 17 : When two (or more) terms have exactly the same radicand, |
| Slide 18 : we call them like radical terms, and we can combine them . |
| Slide 19 : But when the radicands are not identical . . . |
| Slide 20 : . . . the terms cannot be combined. |
| Slide 21 : Practice combining radical terms: |
