Multiplication
and Division of Radicals |
|
When multiplying
radicals, one must multiply the numbers OUTSIDE
(O) the radicals AND then
multiply the numbers INSIDE (I) the
radicals.
When dividing
radicals, one must divide the numbers OUTSIDE
(O) the radicals AND then
divide the numbers INSIDE (I) the
radicals.
 |
Let's try an example. |
| 1. Multiply the outside numbers first |
2 • 3 = 6 |
| 2. Multiply the inside numbers |
 |
| 3. Put steps 1 and 2 together and simplify |
 |
| 4. Therefore, the answer is 72. |

Let's try another one: |
 |
| 1. Divide the outside numbers first. |
 |
| 2. Divide the inside numbers. |
 |
| 3. Put steps 1 and 2 together and simplify. |
 |
| 4. Therefore, the answer is: |
